John Warren Johnson, a longtime science teacher at Newport Harbor and Corona del Mar high schools, has died of congestive heart failure. He was 96.
His son, John Richard Johnson, said his father died Thursday at a hospice in Santa Barbara.
The elder John was remembered as a naturalist who devoted much of his life to the study of moths and butterflies in Southern California.
"He was sharp right up to the end," said John Richard Johnson, 60, in a telephone interview from Santa Barbara on Tuesday. "He was a teacher his entire career and, really, until the day he died. He had a remarkable memory for detail."
So enthralled with the life of insects, John Richard Johnson said, some of his father's students would name a few of the insects after him in his honor.
"From the time he was a boy, he became interested in the natural history of Orange County," his son recalled. "And in later years, he was very active in conserving Newport's Back Bay."
