Hiram Lutz

Hiram Lutz was an enormously wealthy but miserly man, who was also a believer in extraterrestrials.

When Lutz refused to donate money to help a struggling disabled children's home, at Sarah Jane Smith's request, she and the Fourth Doctor disguised themselves as aliens to teach Lutz a lesson about how money was not everything and he should give generously to those in need. (COMIC: The Hoaxers)
