Post-Crisis Chronology

Construction engineer Alan Scott is aboard a train during its test run when a rival engineer, Albert Dekker, blows the train off its track, killing all but Scott. Alan survives because of his ancient, magic green lantern formed from the ancient mystic Starheart. He fashions a ring from the lantern that enables him to tap into its great power. Scott adopts the identity of the Green Lantern I and executes justice on Dekker. Note: This event occurs earlier than its original publication per the timelines in Zero Hour and Green Lantern Secret Files #1 (1998). The origin of Green Lantern was retold in Secret Origins #18. Also shown in JSA: Classified #11. Doomsday Clock #9 (May 2019) identified this event as the cornerstone event in Golden Age of heroes and formation of the Justice Society (taking the place of Superman's debut). In Comic Cavalcade #13 (Winter 1945), Alan claimed that he'd been given the lantern by a group of Tibetan lamas (a theme from this era popularized by the pulp hero, the Green Lama).

All-American Comics #16 (July 1940); Secret Origins vol. 2 #18 (Sept. 1987); Alan Scott: The Green Lantern #2 (Jan. 2024)

1938: Professor Hughes of Midwestern University in Keystone City learns about the Green Lantern and sets out to create his own super-human. He chooses college student Jay Garrick as his subject, taking years to craft an experiment he hopes will transform Garrick by way of "hard water." Jay Garrick meets Joan Williams.

Flash Comics #1 (Jan. 1940); Jay Garrick: The Flash #4 (Mar. 2024)

Plagued by dreams, Wesley Dodds becomes the Sandman. In his first major case, he solves a series of murders committed by an unknown killer called the Tarantula. At the same time, he meets Dian Belmont. NOTES: Before the Sandman Mystery Theatre series, Secret Origins #7 (1986) established the date of the Sandman's debut as June 10, 1939. Since the Crisis on Infinite Earths, the debuts of several heroes (including the Sandman, the Flash and Green Lantern) have been moved earlier to fill the void left by the elimination of the Golden Age Superman and Batman. The Sandman's first published appearance was in New York World's Fair Comics #1, released April 30, 1939, although the story in Adventure Comics #40, which was published in early June 1939, preceded it chronologically (and was probably written first). Dian Belmont's first appearance was in Adventure Comics #47 (February 1940). The Tarantula in Sandman Mystery Theatre story bears little resemblance to the villain of Adventure Comics #40, which was reprinted in Justice League of America #94 (1972).

Adventure Comics #40 (July 1939), Sandman Mystery Theatre #1-4 (Aug.–Nov. 1993)

26 February 1938: The Sandman investigates a series of murders in New York's Chinatown committed by The Face. NOTES: The date of this adventure is established by Dian's diary entry in Sandman Mystery Theatre #5. The villain of the SMT story resembles that of Adventure Comics #44 in name only.

Adventure Comics #44 (Nov. 1939), Sandman Mystery Theatre #5-8 (Dec. 1993–Mar. 1994)

12-13 March 1938: Germany annexes Austria.

13 March 1938: Baroness Paula Von Gunther's husband, Gottfried, is murdered by Nazi agents when he refuses to surrender his wealth. Two months later, Paula receives HIS ashes from the Nazis in a cigar box. Her daughter Gerta is imprisoned in a concentration camp and Paula is forced into service as a slaver and spy in America. These events drive her to insane cruelty.

Wonder Woman vol. 1 #3 (Feb/Mar. 1943)

St. Patrick's Day, 1938: Sandman battles the Brute. Dian becomes involved with the United Way charity.

Sandman Mystery Theatre #9-12 (Dec. 1993–Mar. 1994)

Professor Hughes triggers an 'accident' and activates Jay's metagene. Jay passes out after breathing in the "heavy water" fumes and Hughes takes a sample of Jay's blood, but he gains super-speed powers. When he learns that Joan's father, Major Williams, has been kidnapped, he dons a costume as the Flash and rescues him from Sieur Satan and the Faultless Four. Joan knows Jay's secret identity. Hughes is later approached by Nazi called "Parsifal," who sets him up in a lab in Germany. Hughes gives empowers himself to control the elements, becoming Doctor Elemental. Notes: The date of Jay's debut as the Flash in current continuity is somewhat unclear. Secret Origins #9 (Dec. 1986) established that the accident took place in fall 1939, a few weeks after the German invasion of Poland a few months before his heroic debut in the fall of that year. The timelines in Zero Hour #0 (Sept. 1994) and Flash Secret Files #1 (Nov. 1997), as well as references in Sandman Mystery Theatre, indicate that in post-Zero Hour continuity he debuted in 1938. Golden Age Secret Files #1 (Feb. 2001) complicates matters further by indicating that Jay gained his powers in 1938, but did not become the Flash until early 1940, although another story in that same issue has Jay active as the Flash by November 1938. Many of the Flash's early stories described him as operating in New York City, but most modern accounts show him as having always operated in Keystone City. The Professor (spelled "Hughs") appeared in Flash Comics #1 (Jan. 1940), but "Dr. Elemental" is a new creation.

Flash Comics #1 (Jan. 1940); Secret Origins #9 (Dec. 1986); Jay Garrick: The Flash #4 (Mar. 2024)

April 1938: Lee Travis learns that his godfather, right-wing isolationst Winston W. Smythe, has died and left him a successful newspaper, the New York Globe-Leader. NOTES: The date is approximate; in Secret Origins #5, set in October 1938, Lee Travis says Smythe died "just six months ago."

(Secret Origins #5, Aug. 1986)

Magician Giovanni Zatara and wealthy oil man Tex Thompson (Mister America) begin fighting crime. NOTE: Tex Thompson became Mister America in Action #33. The origin of Zatara was retold in Secret Origins #27; the origin of Tex Thompson was retold in Secret Origins #29.

He's forced to drop out of college and try his hand at professional boxing. NOTE: JSA: Classified #27 places Henry's actual death at 1938. It's uncertain what year his mother was killed. The origin story in Sensation Comics #1 (1942), mentions his parents' deaths in flashback.

Sensation Comics #1 (Jan. 1942), JSA: Classified #26-27 (July–Aug. 2007)

College student Ted Grant is trained in boxing by a man later revealed to be Nat Milligan, the man who trained Jim Harper (the Guardian).

29-30 September 1938: Germany, Italy, France, and Britain sign an agreement in Munich that allows Germany to occupy the Sudetenland areas of Czechoslovakia without opposition beginning October 1. The Czech president is forced to accept it.

13 October 1938: Hitler acquires the Spear of Destiny from a Vienna museum and takes it to Berlin. NOTES: In the real world, the Spear was stored in Nuremberg for the duration of the war. It was seized by Allied forces on April 30, 1945, only hours before Hitler's suicide, and later returned to the Hofsburg in Vienna.

31 October 1938: Lee Travis, now the publisher of the New York Globe-Leader, becomes the Crimson Avenger, aided by his Chinese valet, Wing. NOTES: Some accounts, such as Golden Age Secret Files #1 (Feb. 2001), suggest that the Crimson Avenger was the first costumed hero in current continuity. However, Secret Origins #5 ties the Crimson Avenger's debut to the famous broadcast of Orson Welles' War of the Worlds on Halloween of 1938, which suggests that while the Avenger may have been the first prominently known masked avenger (thanks, perhaps, to Travis' publicity in his own newspaper), but he was actually preceded by several other heroes, including Quicksilver, the Sandman, and (probably) the Flash. The Crimson Avenger and Wing were closely based on the Green Hornet and Kato, adventurers created by Frank Striker and George W. Trendle, who debuted on WXYZ radio in 1936. In the Secret Origins story, the Travis remarks upon his own image, "I look like a combination of the Lone Ranger and the Phantom of the Opera." (The Lone Ranger was the Green Hornet's granduncle, as revealed in a 1947 Hornet radio episode, "Too Hot to Handle.")

Detective Comics #20 (Oct. 1938), Secret Origins #5 (Aug. 1986)

The Sandman battles the Scorpion, son of a Texas farmer who was bought out of his land and then made an outcast by several wealthy businessmen. Dian begins to suspect Wesley of being the Sandman.

Rex "Tick Tock" Tyler develops Miraclo, a wonder drug that gives him super-powers for an hour at a time. He takes out an ad offering his services to those in need as "The Man of the Hour." He will later call himself Hourman. NOTES: Hourman's debut was retold in Secret Origins #16, which asserted that Rex discovered Miraclo in December 1939—after the debuts of Hawkman and the Spectre. This changed with the publication of Sandman Mystery Theatre #29-32 (see below). In his initial appearances, his name was hyphenated: Hour-Man. Adventure Comics #48 was reprinted in Justice League of America #96 (1971).

Adventure Comics #48 (Mar. 1940), Secret Origins #16 (July 1987)

26 November 1938: The New York Globe-Leader publishes an interview between John Law (later the Tarantula) and the Crimson Avenger, which confirms the Avenger's existence and establishes him (probably incorrectly) as the first of the masked adventurers. NOTES: This story indicates that the Crimson Avenger is already using his famous gas gun. According to the 1988 Crimson Avenger mini-series, he did not acquire the gas gun until December 1938; prior to that adventure, he used conventional automatic pistols.

Golden Age Secret Files #1 (Feb. 2001)

7–9 December 1938: The Crimson Avenger clashes with agents of the Dark Cross and captures a prototype of a Bundist secret weapon: a gas gun firing cartridges of knockout gas. "The Crimson" eventually discovers that their leader is really his godfather, Winston Smythe, who had faked his own death  to pursue his criminal activities. Smythe is apparently killed for real by his own bomb, and the Crimson keeps the gas gun as his own signature weapon. NOTES: Roy and Dann Thomas wrote mini-series and the Crimson’s origin in Secret Origins #5, but Smythe’s relation to Lee Travis differs between them: godfather or uncle in the former and grandfather in the latter. Both Who’s Who Update ’88 #1 (Aug. 1988) and Golden Age Secret Files & Origins #1 (Feb. 2001) list Smythe as his’s godfather.

Sandman Mystery Theatre #29 (Aug. 1995)

Sandman Mystery Theatre #30 (Sept. 1995)

Part 3: The Sandman comes to Rex Tyler's aid when the "Man of the Hour" gets in over his head. He later leaves Rex a note dubbing him "Hourman." Rex dons a costume very similar to his later Hourman costume for a masked ball, while Wes Dodds picks a yellow-and-purple outfit similar to the one he will adopt in 1941.

Sandman Mystery Theatre #31 (Oct. 1995)

Part 4, 31 December 1938: Hourman discovers the Sandman's secret identity. They join forces to thwart the kidnapping of Dorothy Bannermain, the wife of Rex Tyler's boss, and Rex decides to do more research on Miraclo before continuing his heroic career.

Spring 1939: Dr. Occult is prompted by the Phantom Stranger to warns Zatara that the rise of costumed “science heroes” could mean the death of “true magic,” and urges him to join the heroes’ ranks. Note: By most other accounts, Zatara had been fighting crime for at least a year by that point.

Sandman Mystery Theatre #37 (Apr. 1996)

Part 2: Wes Dodds meets Ted Knight, a young scientist applying for a grant to perfect the alloy needed to collect his newly discovered cosmic energy.

He flees as far as Opal City before he apparently disintegrates. Ted Knight and Wes Dodds learn that "Smythe" was not his real name. NOTE: A news broadcast mentions that England has formed an alliance with Russia to stand up against further German aggression in Europe. This is not historically correct; although the Russians proposed such an alliance in the spring of 1939, no agreement was reached.

Sandman Mystery Theatre #40 (July 1996)

30 April 1939: The New York World's Fair opens in Queens, New York. The event is marked by the threatening appearance of a masked killer, the "Phantom of the Fair."

Alan Scott (Green Lantern) visits the World's Fair and meets radio reporter Irene Miller, who later becomes his girlfriend.

All-American Comics #18 (Sept. 1940)

The Sandman visits the World's Fair and prevents the henchmen of Wesley Dodds's crooked business partner from stealing an experimental ray gun. NOTES: Released on April 30, 1939, this was the Sandman's first published appearance, although the story in Adventure Comics #40, released in early June, was apparently written first.

New York World's Fair Comics #1 (1939)

1939, Queens: At the New York World's Fair, Wonder Woman leaps to save President Franklin Delano Roosevelt from an assassin. She warns him of encroaching evil, offers her help. Alan Scott is in the audience. Note: The original tale, of Rebirth continuity, presents Wonder Woman Diana. This was influenced by the 2017 film, in which Diana began her career in the early 20th century. But after the publication of New History of the DC Universe #1 (Aug. 2025), post-Crisis continuity was restored and Hippolyta was again the Golden Age Wonder Woman. This event occurs years before Wonder Woman's historical debut, All-Star Comics #8 (Dec. 1941/Jan. 1942).

Wonder Woman #750 (Late Mar. 2020)

Summer 1939: Archaeologist Dan Garrett strikes out as the original Blue Beetle.

While Dian Belmont writes her first pulp story, she and Wesley Dodds read a comic book story about the Sandman and his boy sidekick, Sandy Hawkins, who wear skin-tight yellow costumes. Afterward, Dian is nearly killed when the publishing office is fire-bombed. NOTES: This magazine could have influenced Wes' subsequent costume change — but this story was originally intended to retroactively eliminate the Sandman's adventures in the purple-and-yellow costume from continuity. Subsequent stories, however, have revealed that the Sandman did later adopt Sandy Hawkins and don his purple-and-yellow costume.

Sandman Mystery Theatre #50 (May 1997)

2 September 1939: Janos Prohaska's family is slain by a German fighter attack led by Wolfgang Teppel. Calling himself Blackhawk, Prohaska organizes an independent multinational squadron to fight the Nazis. He and other multinational pilots are organized into a squadron to fight the Nazis by Carter and Shiera Hall. NOTES: Blackhawk was originally published by Quality Comics. His real name was not revealed in his first appearance in Military #1. The name Janos Prohaska, inspired by an actor and stuntman of the sixties and seventies, was given in the Blackhawk: Blood and Iron mini-series (1988). Blackhawk's origin was reprinted in Blackhawk vol. 2 #7 (1990) and retold in Secret Origins #45. The Halls' patronage is a Rebirth invention. The Rebirth Blackhawks first appeared in All-Star Batman vol. 2 #6–9 (2016–17).

NOTES: Hawkman's anti-gravity metal was originally called "Ninth metal"; it became "Nth metal" after the characters' Silver age reintroduction (1961). Hawkman was the only character to appear in every Golden Age issue of All-Star and Flash Comics. His origin in Secret Origins #11 established the date of his debut.

NOTE: It is not clear whether Ultra's original form was the human first shown in Action #13 (his first app.), or the ape in JSA: Classified #20. The latter tale changes the spelling of her first name.
