[mentioned in passing] Died in a laboratory explosion on Luna. A memorial was set up to him and other victims.
Delos D. Harriman
Business tycoon who inspired and largely funded many space-related endeavors, including the first trip to the moon. Harriman is mentioned indirectly in most of the Future History stories, mostly in businesses and institutions bearing his name. In "The Black Pits of Luna", he is referenced indirectly; the Harriman Trust is Richard Logan's employer.
Younger son of Harriman executive Richard Logan, brought to the moon during his father's a business trip. He was older than the name implies, probably about five; he was obviously quite spoiled and used to getting his own way. During a guided tour on the lunar surface, he wandered away and got lost; his older brother Dick Logan eventually found him after other efforts failed.
Dick Logan
Older son of a Harriman executive, and a Boy Scout. He visited the Moon with his family, and was the only one to appreciate the experience. When his younger brother wandered off during an "outside" tour, Dick found him after other efforts failed. There is an implication that he would return to the Moon when he grew up.

Mrs. Logan (no first name)
Woman who accompanied her husband to Luna for a business trip; she hated the experience except for the opportunity to wear scanty formal attire. She referred to herself as "Mother Dear".
