Eando Binder was a great Science Fiction pseudonym, being odd and perhaps just a little futuristic. The truth is it simply meant E. and O. Binder, the two brothers, Earl and Otto. Along with their brother, Jack, the three men would all make contributions to the history of Science Fiction. Jack, the eldest, was an artist who ran his own comics art studio before going to Fawcett Comics to draw Otto’s stories of Mary Marvel.
The two younger brothers were fans of the early Science Fiction magazine, Amazing Stories, and would eventually begin their career selling to T. O’Conor Sloane after Hugo Gernsback was forced out. Their second story when to Gernsback at his Wonder Stories. These two editors along with amateur publications would split Eando Binder’s production until Farnsworth Wright and Weird Tales joined the list in 1935. At the end of their collaboration they would write for Thrilling Wonder Stories and Mort Weisinger, their old pal from amateur days and future editor at DC Comics.

As 1939 approached and SF magazines were sprouting up all over, the Binder name in new magazines like Science Fiction, Future and Super Science Stories. Eando Binder even sold a novel to Argosy. Otto was now doing the writing while Earl acted as literary agent. The early stories composed by both men were over. Otto would go on to accomplish some amazing things, like the first sympathetic robot character, Adam Link, the Via stories, Captain Marvel and Superman comics at Fawcett then DC, the Jon Jarl text stories and many others.
According to Otto Binder: The Life and Work of a Comic Book and Science Fiction Visionary (2003) by Bill Schelly:
Despite the breakup of their partnership, Earl and Otto remained very close. In Earl, Otto was able to see what might have been his fate if he’d gotten married young, stayed in Chicago, and been forced to find employment in a noncreative job.
