Bob Kane was arguably the most successful artist to sell an idea to Jack Liebowitz and Harry Donenfeld aka the publishers of DC comics. Unlike Siegel and Shuster whose experience of achieving worldwide fame as the creative duo behind Superman was tarnished by years of having to bitterly come to terms with the fact that in doing so they had lost ownership of their brain child and millions of dollars in revenue. A very late in the day and miserly annual stipend from a company that had greatly benefited from the efforts of the two Cleveland visionaries was scant consolation.
Robinson put it like this:
Robinson's earliest art contributions to Batman were somewhat compromised by the need to retain the Bob Kane house style and so he emulated Kane's wooden figure-work to a tee. But as his confidence grew and as artists like Irwin Hasen and most importantly Mort Meskin (whose fluid artwork would prove an inspirational touchstone for Robinson) dropped around to their 33rd Street apartment to share drawing boards and deadlines, so Robinson's own distinctively lithe and pleasing style begin to assert itself on his Batman assignments.
