Geoff Miller, longtime editor and one of the original founders of Los Angeles magazine, passed away on Saturday at his Beverly Hills home after a prolonged illness. He was 74.

Miller and David Brown launched the magazine in 1960, which was originally called the Southern California Prompter. A year later, they changed the title to Los Angeles magazine. As The Wrap obit notes, it was a pioneering publication:

Los Angeles was the first “city magazine,” and Miller is credited with helping to create the genre. His publication predated New York magazine by eight years.

“Los Angeles magazine began life with no instruction manual,” Miller later wrote.

Miller worked at Los Angeles magazine for 34 years. He was editor-in-chief from 1974 to 1990, and became publisher in 1990. He retired in 1994. Current Los Angeles editor Mary Melton promises a tribute to Miller in the magazine’s June issue.
