Hollis W. (Mike) Harloff, 55, a resident of Temple Hills and a retired NASA press official, died Aug. 1 at Prince George's General Hospital after being hit by a car the previous day.

Prince George's County Police said Mr. Harloff was walking on 23rd Parkway near his home on July 31 when he was struck by an automobile traveling in the opposite direction. Police said that the driver of the vehicle, Wendell Holmes, 22, of 2003 Shipley Ter. in Washington, was charged with failure to stay to the right of the center line.

Mr. Harloff came to Washington in 1950 as public relations director for the Blinded Veterans Association, moved to New York a year later where he joined a public relations firm and wrote radio scripts.

He returned here in 1956 and joined the public information office of the Civil Air Patrol, later transferring to the Naval Research Laboratory's media relations office where he became deputy chief. He also worked on information projects involving the Vanguard project.

He joined NASA in 1960, and was a press officer at the Goddard Space Flight Center in Greenbelt at the time he retired in 1976.

Mr. Harloff was a native of Evanston, Ill. He was an Army combat infantryman in Europe, where he earned a Purple Heart. His war injuries left him legally blind. After the war, he attended Northwestern University where he earned a bachelor's degree in 1950.

Survivors include his wife, Sally; two sons, Kim and Christopher, and a daughter, Karen Harloff, all of Temple Hills; another daughter, Holly Ender of Washington, and his mother, Alma Harloff of Morton Grove, Ill.
