William A. Travis Jr., 59, the general manager and a director of B. W. Real Estate Inc. of Capitol Hill, died Saturday at his summer home in Rehoboth Beach, Del., following a heart attack.

Mr. Travis began buying and restoring houses on Capitol Hill in the late 1940s. He specialized in properties in that part of the city throughout his career in real estate. Several of his projects have been included on the annual Capitol Hill Restoration Society house tours.

A native of Statesville, N.c., Mr. Travis came to Washington about 1940 and went to work for the Southern Railway. In the late 1940s, he joined the Royal Globe insurance company and became a claims adjuster. At the same time, he began buying properties on Capitol Hill.

Mr. Travis later went into real estate and restoration full-time. He worked for Millburn Donohoe Realty and was manager of Beau Bogan Inc. from about 1963 until 1977. He then joined B. W. Real Estate.

Mr. Travis was a member of the Capitol Hill Civic Association and of the National Democratic Club.

Survivors include three sisters, Betty Sue Travis, of Washington, Patsy Colleen Travis, of Charlotte, N.C., and Molly Allen, of Mayodan, N.C., and two brothers, Robert Travis, of Charlotte, N.C., and Ross Travis, of Dillon, S.C.
