William Coyne, 77, the quiet Democratic congressman who represented the Pittsburgh area for 22 years, from 1980 to 2003, has died.

Mr. Coyne, an Oakland resident, died early this morning of complications from a fall that occurred two months ago, according to Jamie Rooney, his longtime executive assistant.

“Bill was in good health until he fell and hit his head, very good shape,” said Mr. Rooney.

Services are being handled by John A. Freyvogel Sons Inc. funeral home in Shadyside but are incomplete.

Often described as affable, but quiet and self-effacing, Mr. Coyne was an old-fashioned liberal who had a number of behind-the-scenes successes on the House Ways and Means Committee, including earned income tax credits for the poor and industrial development bonds for cities. He also had an admirable record of constituent service.
