owned by Malcolm Wheeler-Nicholson. Wheeler-Nicholson published two of their strips in New Fun Comics #6 (1935): "Henri Duval" and "Doctor Occult". Siegel and Shuster also showed him Superman and asked him to market Superman to the newspapers on their behalf. In October, Wheeler-Nicholson offered to publish Superman in one of his own magazines. Siegel and Shuster refused his offer because Wheeler-Nicholson had demonstrated himself to be an irresponsible businessman. He had been slow to respond to their letters and hadn't paid them for their work in New Fun Comics #6. They chose to keep marketing Superman to newspaper syndicates themselves. Despite the erratic pay, Siegel and Shuster kept working for Wheeler-Nicholson because he was the only publisher who was buying their work, and over the years they produced other adventure strips for his magazines. Wheeler-Nicholson's financial difficulties continued to mount. In 1936, he formed a joint corporation with Harry Donenfeld and Jack Liebowitz called Detective Comics, Inc. in order to release his third magazine, which was titled Detective Comics. Siegel and Shuster produced stories for Detective Comics too, such as "Slam Bradley". Wheeler-Nicholson fell into deep debt to Donenfeld and Liebowitz, and in early January 1938, Donenfeld and Liebowitz petitioned Wheeler-Nicholson's company into bankruptcy and seized it. In early December 1937, Siegel visited Liebowitz in New York, and Liebowitz asked Siegel to produce some comics for an upcoming comic anthology magazine called Action Comics. Siegel proposed some new stories, but not Superman. Siegel and Shuster were, at the time, negotiating a deal with the McClure Newspaper Syndicate for Superman. In early January 1938, Siegel had a three-way telephone conversation with Liebowitz and an employee of McClure named Max Gaines. Gaines informed Siegel that McClure had rejected Superman, and asked if he could forward their Superman strips to Liebowitz so that Liebowitz could consider them for Action Comics. Siegel agreed. Liebowitz and his colleagues were impressed by the strips, and they asked Siegel and Shuster to develop the strips into 13 pages for Action Comics. Having grown tired of rejections, Siegel and Shuster accepted the offer. At least now they would see Superman published. Siegel and Shuster submitted their work in late February and were paid $130 () for their work ($10 per page). In early March they signed a contract (at Liebowitz's request) in which they gave away the copyright for Superman to Detective Comics, Inc. This was normal practice
