Alfred R. Jamison, 91, a golf professional in the Washington area since 1928 who in the 1950s started designing golf courses throughout the region, died of congestive heart failure and multiple myeloma Oct. 31 at his home in Vienna.

Known as "the Hat" because of the felt-tip chapeau with which he hid his prematurely balding head, Mr. Jamison played minor league baseball and golf in his home town of Wilmington, Del., before becoming an assistant pro at the old Bannockburn, Army and Navy, and Kenwood country clubs.

He became a pro at the old Indian Spring Club in 1938, followed by Bradley Hills Golf Club (now Bethesda Country Club) and East Potomac Golf Course. After World War II--which Mr. Jamison spent in Asheville, N.C., as an auditor with the General Accounting Office--he was a pro at the old Officer's Golf Club at Quantico Marine Corps Base and Goose Creek Golf Club.

Merrell W. Whittlesey, The Washington Post's former golf reporter, called Mr. Jamison in the 1940s "never a national threat but a consistently good home pro golfer" and "one of the foremost teachers and stylists in this section."

In the 1950s, he was a partner with architect Eddie Ault in the golf-course design firm Ault and Jamison. He designed or redesigned about a dozen courses in the Washington area, including River Bend Golf and Country Club, Reston National Golf Course, Medal of Honor Golf Course at Quantico and the University of Maryland course.

He remained a design consultant until the early 1990s and continued to play until last month, even after suffering a stroke in 1985.

Mr. Jamison, a member of the Professional Golfers Association since the 1930s, won the PGA Middle Atlantic teacher of the year award in 1986. "You don't 'teach' golf, you train," he told The Post in 1993. "You don't teach any sport."

Among his avocations were playing the ukulele and piano, ballroom dancing and pool.

His first wife, Lucille Jamison, died in 1974. His second wife, Marie Jamison, died in 1987.

Survivors include his wife of nine years, Faye Jamison, of Vienna; two sons from his first marriage, Robbie, of Manassas, and Ron, of San Jose; two daughters from his first marriage, Mary Lou Williams of Centreville and Judy Heiting of Lexington, S.C.; two stepsons, Jason and Tony Ellis, both of Winter Park, Fla.; two sisters; and eight grandchildren.
