[1][11] Binder spent from 1941 to 1953 with Fawcett, writing "986 stories ... out of 1,743, over half the entire Marvel Family saga", per comic-book writer-editor E. Nelson Bridwell.

He wrote for numerous other Fawcett features, as well as many two-page text fillers that were required in comics in order to be eligible for magazine postal rates.

His text stories in Captain Marvel Adventures, under the "Eando" pseudonym, starred Lieutenant Jon Jarl of the Space Patrol.

[1][4] During his time at Fawcett, Binder co-created with Swayze and C. C. Beck such characters as Mary Marvel, Uncle Dudley, Mr. Tawky Tawny, Black Adam, and Mr.

For Timely Comics, the 1940s company that would evolve into Marvel Comics, he [co-]created Captain Wonder,[14] the Young Allies, Tommy Tyme and the patriotically themed superheroine Miss America,[15][16] and wrote for stories starring Captain America, the Human Torch, the Sub-Mariner, the Destroyer, the Whizzer, and the All-Winners Squad.

[1][4] For Quality Comics, Binder co-created Kid Eternity, and wrote Blackhawk, Doll Man, Uncle Sam and Black Condor stories.

His science fiction for EC Comics includes "Lost in Space", illustrated by Al Williamson, in Weird Science-Fantasy #28 (March–April 1955).

[18] Binder and artist Al Plastino collaborated on the Superboy story in Adventure Comics #247 (April 1958) that introduced the Legion of Super-Heroes, a teen superhero team from the future that eventually became one of DC's most popular features.

The Binder character, drawn by C. C. Beck, meets a young Billy Batson and is astonished that the boy, who has been missing for 20 years, is still a kid.

[28] He first discussed this hypothesis in his 1968 book Flying Saucers Are Watching Us (later called Unsolved Mysteries of the Past, Tower Publications; reissue edition, 1970).

The book is illustrated by Milton Caniff Award winning EC/Creepy/MAD artist Angelo Torres and the much acclaimed Austrian sculptor and speed painter Stefan Koidl.

All the money I made from the Marvels and had saved up went down the drain when, in 1960, I invested as junior partner in publishing Space World, a magazine about astronomics ...

The mag lasted some 16 issues, during which time Bill Woolfolk and I had put in more money—I mortgaged my house—all paid up by Cap—and borrowed, etc., but we never got the lucky break.

[32]In 1973, Binder worked for Vincent Fago's Pendulum Press, adapting classic science-fiction stories into comic book format, including Frankenstein, The Invisible Man, The Time Machine, 20,000 Leagues Under the Sea, and The Mysterious Island.

[1] He died in Chestertown, New York, on October 13, 1974, leaving behind, counted Bridwell, "almost 50,000 pages of comics" comprising "over 1,300 scripts for Fawcett" and "more than 2,000 for 20 other publishers", including "some 93 heroes in 198 magazines".
