Stephen Wilhite was merely trying to solve a technical problem when he invented the GIF, or graphics interchange format, in 1987. As a programmer at the computer-services firm CompuServe, he was seeking a way for users of incompatible computers to share graphics files.
The first GIF he created was unspectacular—a picture of an airplane. Only much later was the technology adapted for the brief, looping animations that jazz up social-media postings.
Mr Wilhite, who died March 14 of Covid-19 at the age of 74, 'never got 1 cent' out of his invention, said his wife, Kathaleen Wilhite. Nor, she said, did he complain about not making a fortune: 'He was just so proud that he had done that.'
He did win a Webby lifetime achievement award in 2013 for inventing the GIF. At the insistence of his wife, he rented a tuxedo for the ceremony. He used the occasion to inform the world that GIF is pronounced like Jif, the peanut butter brand.
Around the age of 51, he retired after suffering a stroke. He enjoyed tinkering with a model train layout at his home ain Milford, Ohio.
