Donald Brown

Donald Brown was a human scientist who served in the United Federation of Planets' Federation Sciences Research and Development in the 24th century.

From 2353 to 2364, he was assigned to the Digarius V research base on Digarius V under the command of Richard Anderson. He was in charge of the new laser project which turns a planet like Venus to a habited planet with oxygen. But Johnson was skeptical saying that Venus was the hottest planet in the Solar system. But Brown said exactly, using their new equipment, they can ignore the hotness of the Sun.

Later in 2364, when Anderson ordered him to check the laser, the laser malfunctioned and severely injured him. He was beamed up to the Valentine's sickbay but they could do nothing, he died of his injuries.

He was played by Arthur Young.
