Let it not go without mention ...
"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." Full obituary and photo in Washington Post June 13, 2007
Thank you, Mr. Wizard, for many an inspiring Saturday morning.
