====1970====
===January, 1970===
  * District Attorney Larry Jordan is gunned down by Joe Parsons. Helen Jordan dons the Air Wave costume for one case to bring her husband's killers to justice. [DC Comics Presents #40]
  * Gregori Arcane is blown up by a mine, but is patched together by his necromancer brother Anton Arcane to become the Frankenstein-like creature called the Patchwork Man, and is kept imprisoned for ten years. [Swamp Thing #3]
  * After his last recorded case at this time, Johnny Peril spends the next decade searching out dark secrets forbidden to most men, possibly while working at the Grimoire Academy of Applied Learning. [Unexpected #117]
===March, 1970===
  * During Spring Break, Clark Kent and his friend Ted O'Hara travel by Jeep through the Southwest. Donning a buffalo skin and headdress, Ted is possessed by the spirit of an American Indian medicine man with magical powers and helps Dr. John Navarro (the great-great grandson of the medicine man) in Cedarville to complete an operation. //Note: Ted O'Hara is originally from Smallville and was a friend of Clark's when they were children, appearing in More Fun Comics #102 and #103 and others. His full name comes from Superboy #140.// ["Healing Hands from Beyond," Action Comics #410]
===May, 1970===
  * Lorna Martin learns that Clark Kent is Superboy using her ESP powers, but keeps the secret to herself. Returning to Dimension 7 at the end of the semester, she asks the Council of Mentors to allow her to bring Superboy back with her, but her request is denied, and she remains there for years. ["The Girl Who Worshipped Clark Kent," Action Comics #411]
  * May 1: U.S. troops invade Cambodia.
  * May 4: Four students at Kent State University in Ohio are killed by National Guardsmen at a protest against U.S. incursion into Cambodia.
  * May 6: Cliff Baker is born to Buddy Baker (Animal Man) and his wife Ellen Baker.
  * May 14: Prof. Thaddeus V. Maxwell tries to prove that his student Clark Kent is Superboy, but Clark outwits him by inwardly renaming himself Superman in order to thwart a lie-detector test. On that same day, the school for underprivileged youth begun by Marla Harvey is completed, and Superman dedicates it to the same young woman who, one year earlier, had challenged Superboy to become a Superman. //Note: The world would not officially acknowledge Superboy as Superman until the next year.// ["Clark Kent's College Days," Superman #125; "The Day Superboy Became Superman," Action Comics #393]
===June, 1970===
  * June 3: 15-year-old Jimmy Olsen leaves his home in Mapleton to live in nearby Metropolis for the summer, travels back in time 20 years to Krypton and becomes Kal-El's babysitter, and upon his return Superman gets him a job at the Daily Planet as a copy boy. //Note: It is evident from the Jimmy Olsen story in Superman Family #218 that Jimmy was a copy boy at the Daily Planet for some years before he became a cub reporter there. The 2nd story in Superman's Pal Jimmy Olsen #38 also reveals that Jimmy was a copy boy as a teenager when he met Superman. Although Superman does befriend Jimmy at this time, he does not give him a signal watch for two more years. Since Jimmy continues to go to high school in Mapleton, he probably only has his Daily Planet copy boy job during the summers, unless he commutes after school into Metropolis each day.// ["How Jimmy Olsen First Met Superman," Superman's Pal Jimmy Olsen #36; date from Superman's Pal Jimmy Olsen #84]
  * June 24: The Senate repeals the Gulf of Tonkin Resolution.
===July, 1970===
  * Selina Kyle, a young flight attendant for Speed Airlines, sustains a head injury that causes her to have amnesia. She soon turns to crime, eventually establishing a reputation for herself as a master thief called the Cat, later known as the Catwoman. ["The Secret Life of the Catwoman," Batman #62 (December, 1950-January, 1951)]
===September, 1970===
  * Jim Rook finally gets a record deal. [Whatever Happened to Nightmaster?]
  * Lex Luthor escapes from reform school, and Superman tries to track him down. Clark Kent meets Billy Cramer, a younger shy boy from Smallville. Superman catches Lex Luthor and takes him to prison, since he turns 21 later this month. Ducky Ginsberg is crippled in a drunk driving accident he caused. //Note: This story reveals that Lana Lang has already transferred from Metropolis University to Hudson University.// ["Dreams and Schemes and Feeling Proud," Superman: The Secret Years #1]
  * Billy Cramer moves into Clark's room as his new roommate, while Tommy Lee moves in with Dave Hammond. At Luthor's trial, he is sentenced to 10 years in the state penitentiary. Billy helps Clark avoid being the target of Steve Powers' revenge scheme. ["Reach Out and Touch," Superman: The Secret Years #2]
  * September 15: Bruce Wayne, musing on how to inspire fear in criminals, witnesses a bat flying through his open window. This seminal event inspires him to become the Batman. //Note: The date is derived by the full moon, which must be the last full moon before the Batman's first appearance in October, 1970.//
  * September 20: Clark Kent meets the beautiful Lori Lemaris, who is secretly a mermaid and who ignores Billy Cramer's presence completely. Later, when Clark's biology class is touring a floating aquarium, a boiler explodes, damaging the aquarium and forcing everyone to evacuate. While herding all the fish into a net, Superman sees Lori Lemaris still underwater and calming a giant octopus. ["The Girl in Superman's Past," Superman #129; "Reach Out and Touch," Superman: The Secret Years #2]
  * Clark Kent begins dating Lori Lemaris. Meanwhile, Superman tries to crack the Bermuda Triangle mystery and discovers a thriving community of people who fell through a rip in space in the Bermuda Triangle into another dimension. Since they are happy there, he vows at their request not to let anyone know what happened to them. Clark reveals his secret identity of Billy Cramer, since he is his new best friend. ["The Girl in Superman's Past," Superman #129; "Reach Out and Touch," Superman: The Secret Years #2]
  * Superman gives Billy Cramer a special ultrasonic whistle to summon his help whenever he needs it. Over the next few months, Superman and Billy make a great team. ["Terminus," Superman: The Secret Years #3]
===October, 1970===
  * October 14: The Batman, wearing a crude-looking original costume with longer ears and a bigger utility belt, makes his first public appearance. In his very first case, the Batman is tricked by a thief named "Slugsy" Kyle and is knocked out and briefly captured after he trails him to the Gotham Glass Works factory. Finally, the Batman manages to outwit Kyle and capture him. Soon after, the Batman stops two bank robbers on a rooftop after they robbed the First Federal Bank. Capturing them and tying them up, the Batman leaves them for Police Commissioner James W. Gordon and his men to find, along with a hastily scrawled note identifying himself only with a bat-symbol, which gives him the name of the Bat. Officer Collins, spotting the Batman fleeing the scene, fires off two shots until Gordon stops him. //Note: The Batman's first case supposedly takes place on December 4, according to 1976 Super DC Calendar, but this date is not a full moon in 1970, and it seems to be nearly two months too late to be Batman's “first case,” so it's possible this date refers to another event. The Batman's public debut takes place exactly 15 years before the events of Batman #400, which shows Batman celebrating a major anniversary of his debut. After getting out of jail in 1974, Kyle becomes the villain known as the Clock. Although the scene of Batman fighting two crooks on a rooftop is based on "The Case of the Chemical Syndicate" from Detective Comics #27, it cannot be that case, which actually occurs on Earth-1 in a different way in 1978, as depicted in Detective Comics #387. The appearance of a full moon places this story on October 14, 1970. Originally using a crude bat-costume with large bat-ears as an initial test, Batman creates over the next couple of months a sleeker-looking costume with smaller bat-ears that becomes his defined look. He also begins building his crime-fighting tools, such as the Batcave, the Batmobile, and the Batplane, keeping him busy until he has his first official case in December. However, Batman's exploits are largely unknown by the general public until mid-1971, and the Batman is believed to be an urban myth until then. Since there is no clear demarcation between the Golden Age and Silver Age Batman, and since the Silver Age Batman is generally accepted to have had many of the same early adventures as the Golden Age Batman, it's likely that his career begins earlier than previously believed. It is worthwhile to note that Dennis O'Neil once stated that Bruce Wayne became Batman before he turned 21 years old, which would happen on February 19, 1971, just four months after this event.// ["The Legend of the Batman: Who He is and How He Came to Be," Batman #1 (Spring, 1940); "Batman's First Case," Detective Comics #265 (March, 1959); "Earth: Without a Justice League," Justice League of America #37 (August, 1965); "The Man Behind the Mask," The Untold Legend of the Batman #3 (September, 1980); "Resurrection Night," Batman #400 (October, 1986)]
===November, 1970===
  * November 3:
    * Harvey Dent is elected as Gotham City's youngest district attorney.
    * The Batman, wearing a new, permanent costume, visits the offices of Police Commissioner James W. Gordon and offers his services to the police, but Gordon rebuffs him, telling him that police work isn't for amateurs. The Batman then visits Harvey Dent, the newly elected district attorney on the eve of his election, and makes the same offer, which Dent accepts. The Batman and Harvey Dent begin a friendship and secret working relationship that lasts for the next six months. //Note: The Batman's real but relatively unexplored friendship with Harvey Dent inspires this speculation.// ["Batman and Robin's Greatest Mystery," Detective Comics #234 (August, 1956); "The Crimes of Two-Face," Detective Comics #66 (August, 1942)]
  * The Batman's second official case is the Venice Murder Case. //Note: Nothing is known about the Venice Murder Case, other than that the Batman obtained a gondola as a trophy.// ["The 1,000 Secrets of the Batcave," Batman #48 (August-September, 1948)]
===December, 1970===
  * Pete Ross, visiting from Raleigh University, is reunited with Clark Kent and meets Billy Cramer. Later, Clark visits Billy's family's second home in Florida during winter break. ["Terminus," Superman: The Secret Years #3]
  * December 4-6: The Batman encounters an extortionist called Doctor Death, who uses a death pollen to extract a tribute from wealthy people. After the Batman pursues the villain to his house, Doctor Death dies in a fiery inferno that consumes his entire laboratory and home, but Doctor Death escapes via a secret passage after sustaining first-degree burns. Unknown to the Batman, Doctor Death is really an agent of the true mastermind, Dr. Karl Hellfern, who averts all suspicions by working through proxies. Around this time, the Batman is considered an outlaw by the police. //Note: There is a reference to the Batman battling a Doctor Death in his first year in Untold Legend of the Batman #3, but since the Earth-1 Doctor Death is actually introduced for the first time later on in a present-day story, the original Doctor Death is likely a different man acting as an agent for Dr. Karl Hellfern, whose reputation remains intact.// ["The Batman Meets Doctor Death," Detective Comics #29 (July, 1939); "The Man Behind the Mask," The Untold Legend of the Batman #3 (September, 1980)]
  * December 12: The Batman, discovering that Doctor Death is still alive, encounters him again and recovers stolen diamonds from the widow of the man he killed (secretly at the behest of Dr. Karl Hellfern), before capturing him for the police. //Note: After this story, Dr. Karl Hellfern decides to forgo his risky extortion schemes for over a decade, concentrating instead on building a legitimate front business while secretly selling his formulas to the underworld.// [The Batman, Detective Comics #30 (August, 1939)]

====1971====
===January, 1971===
  * At Raleigh College, Lois Lane is a new reporter at the Raleigh Review, where she is assigned three stories as part of a hazing process. The first is a story on how she joins the men's fencing team. Coincidentally, Superman is visiting his friend Pete Ross (who is captain of the men's fencing team) and ends up losing a match to Lois while disguised as Pete because of a piece of kryptonite, enabling her to join the team. Soon after, Superman frightens off a fleet of Serpent Galaxy aliens from invading Earth by creating a red comet, inadvertently giving Lois her next scoop when she discovers that comet, dubbed the Lois Lane Comet. Then Superman is affected by a type of red kryptonite that changes him into any animal he thinks of, changing him into a pterodactyl and then a saber-tooth tiger. Lois, taking pictures of Superman in those ancient animal forms, gets her third scoop and is named co-editor of the Raleigh Review. ["Lois Lane's College Scoops," Superman's Girl Friend Lois Lane #55]
  * January 26: The Batman battles his first costumed foe, the Monarch of Menace, who manages to outwit both the police and the Batman during his crime-spree before vanishing without a trace.

["The Monarch of Menace," Detective Comics #350 (April, 1966); "The Case Batman Failed to Solve," Batman #14 (December, 1942-January, 1943)]
===February, 1971===
  * February 1-7: The Batman encounters Prof. Hugo Strange for the first time, foiling a crime wave enabled by a thick, heavy artificial fog created by Strange's machine.

[The Batman, Detective Comics #36 (February, 1940)]
  * Clark Kent and Lois Lane, leading student reporters at their respective colleges, are invited to meet Daily Planet reporter/editor Perry White in Metropolis. While there, they meet copy boy Jimmy Olsen, and Perry shows them a //Gotham Globe// headline about the Batman in Gotham City, which is the first time they've heard of the Batman. //Note: This is speculation based on a flashback in World's Finest Comics #271 that must take place about a year before Lois starts working at the Daily Planet.// ["The Secret Origins of the Superman and Batman Team," World's Finest Comics #271 (September, 1981)]
===March, 1971===

  * March 12-13: While testing out the Batmobile, the Batman saves the lives of the Jones family, who decide to name their newborn baby after him, calling him Batman Jones. On the way back to Gotham City, the Batman stumbles upon a spy plot to begin an international crisis by blowing up a foreign ship, the //Ronij//, and prevents that from happening. Discovering that the head of the foreign spies is Count Grutt, the Batman confronts Grutt, only for the count to accidentally impale himself upon his own sword. ["The Career of Batman Jones," Batman #108 (June, 1957); The Batman, Detective Comics #37 (March, 1940)]
  * The Batman takes in a teenage boy named John Vance after he becomes a witness to a bank robbery. After Batman disguises him in a smaller Batman costume, Vance calls himself Batman, Junior and helps Batman take down Birrel Binter, the head of the bank robbers, but Vance also lets slip an important clue to his identity by revealing he is a school athlete, which would cause him trouble years later. ["Batman, Junior," Detective Comics #231 (May, 1956)]

[The Giants of Hugo Strange, Batman #1 (Spring, 1940)]
  * May 11: During the trial of Sal "Boss" Maroni, District Attorney Harvey Dent is injured when Maroni throws a bottle of acid at his face, but the Batman deflects it, keeping it from hitting him full on. However, the left side of his face and his left hand are hideously scarred, and he is rushed into surgery. Afterward, Dent recovers for one month wrapped in bandages. //Note: The Earth-2 Harvey Dent is named Harvey Kent. The Earth-2 Boss Maroni is called Boss Moroni.// ["The Crimes of Two-Face," Detective Comics #66 (August, 1942); "The Secret Origin of Two-Face: Double Take," DC Super Stars #14 (May-June, 1977)]

Clark determines to propose to her and tell her his secret identity, but he is restricted to his dormitory as part of a fraternity initiation. He creates a diversion allowing him to leave, and after bringing Lori to a romantic spot by the seaside, Clark proposes. Lori reveals she knows he is Superman but says they cannot marry. Feeling jealous, Superman follows her to her trailer house and hears her sending messages, concluding that she may be a spy. Searching her trailer after she leaves, Superman finds a large water tank and, realizing she is a mermaid, determines to confront her. ["The Girl in Superman's Past," Superman #129; "Terminus," Superman: The Secret Years #3]

After he restores the dam, Superman returns to Lori's trailer, where she explains that as a mermaid from Atlantis she possesses telepathy. Every 100 years someone is chosen to go to the surface world to report on its progress. Superman and Lori Lemaris share one last kiss underwater, and she returns to her people. ["The Girl in Superman's Past," Superman #129; "Terminus," Superman: The Secret Years #3]
    * While moping over the loss of Lori Lemaris, Superman learns of a tsunami in in the South Pacific and is about to save everyone on the resort island of Pandango when he hears Billy Cramer's whistle and sees he is trapped in a burning building. After saving the island from the tsunami, Superman races back to Metropolis only to find that Billy died from suffocation in the fire. He learns from a police officer that Billy charged into the burning building to save a baby. Superman goes into seclusion over the summer, feeling that this is one of his greatest failures. ["Terminus," Superman: The Secret Years #3]

  * June 7-11: The Batman battles a vampire known only as the Master Monk after he kidnaps Bruce Wayne's fiancee, Julie Madison. //Note: The Master Monk is probably not the same vampire known as the Monk, whom Batman encounters in the 1980s.// [The Batman, Detective Comics #31 (September, 1939); The Batman, Detective Comics #32 (October, 1939)]
  * June 12: Harvey Dent's bandages come off, and he learns that his surgery has failed to save his face. The trauma leads him to become a criminal called Two-Face, using Boss Maroni's two-headed silver dollar to let chance decide his every action, scarring one side of the coin to represent evil. Two-Face spends the next month hiring a gang and establishing a secret room that is half-beautiful and half-ugly to act as his hideout. ["The Crimes of Two-Face," Detective Comics #66 (August, 1942)]

  * July 11: One month after their last encounter, Batman and three security guards corner the Red Hood at the Ace Chemical Processing Plant next to the Monarch Playing Card Company, which the Red Hood has just robbed, completing his goal of stealing $1,000,000. Escaping by jumping into a catch basin full of chemical wastes, the Red Hood swims out to the river, then returns home to discover that the chemicals have caused his hair to become green, his skin chalk-white, and his lips ruby-red. Taking inspiration from his appearance and the playing card company he robbed, he forms the identity of the Joker. The Batman is unable to solve the mystery of the Red Hood's identity for a few years, hardly guessing that he becomes his arch-enemy, the Joker. ["The Man Behind the Red Hood," Detective Comics #168 (February, 1951)]

  * July 15-16: While the Haly Circus is in Newtown, John and Mary Grayson fall to their deaths during a trapeze act before 10-year-old Dick Grayson's eyes. After overhearing that his parents were murdered, Dick plans to go to the police, but the Batman takes him in for his own protection, since "Boss" Zucco owns the police in this town. After Dick pleads with the Batman to train him so he can avenge his parents' deaths, the Batman brings Dick to the Bat-Cave where he has him swear an oath to fight crime and always remain righteous. The Batman then reveals his identity of Bruce Wayne. The next day, after obtaining permission from Dick's aunt, Harriet Cooper, Bruce becomes Dick's legal guardian. The Batman then begins training Dick over the next few months. ["Robin the Boy Wonder," Detective Comics #38 (April, 1940); "The Origin of Robin," Batman #213 (July-August, 1969)]
  * July 16-17: The Batman confronts Two-Face, still believing that his friend Harvey Dent can be redeemed, but Two-Face tries to kill him twice. Finally, when Two-Face flips his coin to determine whether he should continue as a criminal or give himself up to the law, the coin lands on its side, leaving the decision to fate instead of chance. //Note: Although Robin the Boy Wonder appears in the original version of this story, on Earth-1 Dick Grayson has not yet become Robin at this time and plays no role in this case.// ["The Crimes of Two-Face," Detective Comics #66 (August, 1942)]
  * July 28: The Batman first meets the Catwoman, originally known as the Cat, when she steals a valuable emerald necklace on a yacht. //Note: This is Dick Grayson's first mission assisting the Batman, though this takes place before he becomes Robin.// [The Cat, Batman #1 (Spring, 1940); "The Women in Batman's Life," Batman #208 (January-February, 1969)]
===August, 1971===
  * August 12: Missing for 11 weeks, Superman stews in regret and spends some time in the other-dimensional world beyond the Bermuda Triangle while Perry White tries to track down the reason for Superman's disappearance and is given Billy Cramer's whistle by Inspector Henderson.

Perry and Henderson summon Superman from the Bermuda Triangle dimension using the whistle. Superman battles Luthor, who has given himself powers equal to a Kryptonian's, while it is broadcast on worldwide television. Luthor supposedly kills Superman and destroys the satellites. Superman then reveals he was playing dead, and he demands to be called Superman from now on instead of Superboy, which most people were still calling him despite his age. Perry White becomes editor-in-chief of the Daily Planet after George Taylor's retirement at age 65. ["Beyond Terminus," Superman: The Secret Years #4]

  * During the time Clark Kent finishes his final year at Metropolis University, Superman establishes a worldwide patrol and begins to focus less specifically on Metropolis, so that by mid-1972 Metropolis is not known as Superman's definite home any longer, but only one possible home base. Superman also begins evaluating which city he wants to make his home once he's graduated, and he tries out several cities for days or weeks at a time over the next year, reinforcing the idea that Superman hasn't chosen a permanent home base yet.

Returning to Metropolis, Superman wonders if he is a wrestler called the Masked Superman, and he assumes his identity. After discovering that the Masked Superman was only a fan of his, Superman searches for the wrestler all over the world and finds him an amnesiac shipwrecked on an island, then uses a fear tactic to restore his memory before bringing him home. Superman, fearing he might be Jud "Super-Thief" Blake, the most wanted criminal, assumes Blake's identity and leads his gang on robberies, only to return the stolen loot later. Superman soon learns that the real Blake was killed in a police ambush a year ago, and his identity has since been assumed by a disguised FBI agent who had been planning to round up Blake's gang and the fences all at once, before being called away for a special FBI conference. Since he's had no luck discovering his old identity, Superman invents a new one, donning glasses and a blue suit and planning to call himself reporter Cal Lewis. But he is immediately recognized as Clark Kent, and Superman realizes that someone has been impersonating him. Superman takes the fake Clark Kent's place and takes down the spy-chief and her gang who ordered the impersonation in the first place.
