William T. Wiley — a founder of the Bay Area Funk art movement who expanded into every medium and style of creation from watercolor to printmaking to giant sculptures in a career that lasted from 1960 until just a few months ago — died Sunday, April 25, at Marin General Hospital.

His death was due to complications from Parkinson’s disease, which he’d suffered from since 2014, said his son, Ethan Wiley. He was 83.

A painter with a unique style developed at an early age, Wiley had exhibited at the San Francisco Museum of Modern Art in 1960 when he was 23 and still an undergraduate at the San Francisco Art Institute. Since then, SFMOMA has come to own 50 of his pieces, with eight of them — in mediums from ink on felt and leather to etching on paper — on display in a designated gallery since the museum reopened in March.
