Simon and Kirby creations for other comics publishers include Boys' Ranch, Fighting American and the Fly.

[4] Harry Simon moved to Rochester, then a clothing-manufacturing center where his younger brother Isaac lived,[5] and the couple had a daughter, Beatrice, in 1912.

[11] There, Simon took a room at the boarding house Haddon Hall, in the Morningside Heights neighborhood of Manhattan, near Columbia University.

Sometime afterward, his boss, art director Harlan Crandall, recommended Simon to Lloyd Jacquet, head of Funnies, Inc., one of that era's comic-book "packagers" that supplied comics content on demand to publishers testing the new medium.

[14] During this time, Simon met Fox Feature Syndicate comics artist Jack Kirby, with whom he would soon have a storied collaboration lasting a decade-and-a-half.

Speaking at a 1998 San Diego Comic-Con panel, Simon recounted the meeting: I had a suit and Jack thought that was really nice.

In the early 2000s, original art for an unpublished, five-page Simon and Kirby collaboration titled "Daring Disc", which may predate the duo's Blue Bolt, surfaced.

[18] Captain America Comics #1 (March 1941), going on sale in December 1940[19] – a year before the bombing of Pearl Harbor but already showing the hero punching Hitler in the jaw[20] – sold nearly one million copies.

[22] After the first issue was published, Simon asked Kirby to join the Timely staff as the company's art director.

[25] Fearing that Goodman would not pay them if he found out they were moving to National, the pair kept the deal a secret while they continued producing work for the company.

The ongoing "kid gang" series Boy Commandos, launched later that same year, was the team's first National feature to graduate into its own title.

[40] Afterward, he reported for duty with the Combat Art Corps in Washington, D.C., part of the Coast Guard Public Information Division.

He was stationed there in 1944 when he met New York Post sports columnist Milt Gross, who was with the Coast Guard Public Relations Unit, and the two became roommates in civilian housing.

With Gross as his writer collaborator, Simon produced Adventure Is My Career, distributed by Street and Smith Publications for sale at newsstands.

[44] As superhero comics waned in popularity after the end of World War II, Simon and Kirby began producing a variety of stories in many genres.

In partnership with Crestwood Publications, they developed the imprint Prize Group, through which they published Boys' Ranch and launched an early horror comic, the atmospheric and non-gory series Black Magic.

[48] While the comic book initially portrayed the protagonist as an anti-Communist dramatic hero, Simon and Kirby turned the series into a superhero satire with the second issue, in the aftermath of the Army-McCarthy hearings and the public backlash against the Red-baiting U.S.

[46] The partnership ended in 1955 with the comic book industry beset by self-imposed censorship, negative publicity, and a slump in sales.

[54] In 1968, Simon created the two-issue DC Comics series Brother Power the Geek, about a mannequin given a semblance of life who wanders philosophically through 1960s hippie culture.

[55] Superman editor Mort Weisinger harbored an admitted dislike for the hippie subculture of the 1960s and felt that Simon portrayed them too sympathetically which helped to bring a quick end to the title.

Shieldmaster, under the direction of Joe's son, Jim, was also published in the comic books Futura and Étranges Aventures.

Simon is among the interview subjects in Superheroes: A Never-Ending Battle, a three-hour documentary narrated by Liev Schreiber that premiered posthumously on PBS in October 2013.
