Don Herbert, 89, who as television's Mr. Wizard was for many years one of the nation's foremost popularizers of science, particularly noted for his ability to attract, inspire and hold the interest of children, died June 11 at his home in the Los Angeles area.
A son-in-law, Tom Nikosey, said Mr. Herbert died of cancer.
Once an aspiring actor, Mr. Herbert used gifts of showmanship, imagination and manual dexterity to create demonstrations that satisfied the senses, expanded the mind and provided insight into the workings of nature.
People of all ages remained enthralled by his television appearances, which included brief science news flashes for adults, a number of TV science specials and "Watch Mr. Wizard," the long-running children's show that transfixed the baby-boom generation.
