Analysis of information sources in references of the Wikipedia article "Humphrey the Whale" in English language version.
For a time, Humphrey didn't have a name -- until the Chronicle reporter assigned to the story christened him.
Birney Jarvis, who covered the whale for its entire 26-day visit, recalled that everyone he talked to wanted to know the whale's name, and that it was taking up interviewing time.
"So I decided to name him," Jarvis said. "I said to myself, 'Humpback ... Humphrey.' It just seemed to fit." Jarvis said he credited the name to a Rio Vista restaurateur he was interviewing, who didn't mind accepting the honor.
