The son of muralist and illustrator Denman Fink, he was born in Brooklyn and raised in the Northeast. The family moved to Coral Gables, Florida, in the early 1920's, where Denman Fink took part in the design of the community. Robert Fink helped his father in the design of a national advertising campaign for the community, but the Depression hindered the advancement of this project. He became a student at Miami University, where his father subsequently taught, and then moved to New York, where he studied at the Art Students League and then became a magazine and advertising illustrator. Several books carry his illustrations, including Displaying 750 of 1986 characters.
