Werner Drewes, 85, a painter and printmaker and retired university professor who had lived in this area since 1972, died June 21 at the Fairfax Hospital ACCESS facility in Reston after a heart attack. He lived in Reston.

In 1969, he gave a one-man show of 36 woodcuts at the National Collection of Fine Arts here. His two most recent showings were an October 1984 retrospective of "Sixty-five years of Printmaking" at the Smithsonian Institution's National Museum of American Art, and an exhibit in Munich that launched the publication of his collected prints. His works appear in galleries in this country and abroad.

A critic, writing in The Post in 1969, said of Mr. Drewes' one-man show that his woodcuts "vary in content and style from portraits to cityscapes and landscapes, from representational and semiabstract to totally abstract approaches."

Mr. Drewes spent 19 years on the faculty of Washington University in St. Louis, where he was first year program director and design professor at the fine arts school, before retiring in 1965.

Before that, he had taught at Columbia University, Brooklyn College, the Master Institute of United Artists in New York and the Institute of Design in Chicago.

Mr. Drewes was a native of Germany and served in that country's army during World War I. In the early 1920s, he studied at the Staatliches Bauhaus in Weimar under Johannes Itten, Paul Klee, and Oscar Schlemmer, and later at the Bauhaus in Dessau with Wassily Kandinsky. He worked and exhibited in Frankfurt before moving to this country in 1930. During the 1930s, he worked for the old Works Progress Administration.

His first wife, the former Margarete Schrobsdorff, died in 1959. Survivors include his wife, the former Mary Louise Lischer Terhune of Reston; three sons by his first marriage, Harald, of Denver, Wolfram, of Bethesda, and Bernard, of Upland, Calif.; eight grandchildren, and a great-grandchild.
