Helen Hollers, a White House administrative assistant who served under nine presidents from Harry S. Truman to George H.W. Bush, died Sept. 18 at her home in Washington. She was 95.

The cause was cardiopulmonary arrest and arteriosclerotic vascular disease, said her niece, Harriet Husemann.

Mrs. Hollers retired in 1993 after more than 40 years at the White House. For most of her career, she worked in the office of the president’s appointments secretary.

Helen Lucille Husemann was born in Lindsay, Neb., and attended what now is Nebraska’s Wayne State College.

She came to Washington in the 1940s and was a stenographer-typist at the Department of Agriculture before moving to the White House.

In retirement, she lived part time in St. Petersburg, Fla.

She was a member of the Catholic Church of the Annunciation in Washington.

Her first husband, Berthold N. Colle, died in 1967. Her second husband, retired Army Col. Harold B. Donaldson, died in 1971. Her third husband, Ralph Harvey Hollers, died in 1998.

Survivors include two stepdaughters, Sarah Donaldson Weeks of Alamo, Ga., and Dr. Karyne Messina of Washington.
