The date February 18, 1930 probably doesn't stand out particularly in your mind, but it certainly does in mine. For that's the day my father, Clyde Tombaugh, a farmboy-turned-astronomer, discovered Pluto, becoming the first American to find a planet. In this slide show of old family photos, follow the trajectory of my father's remarkable career, which, in its way, began and ended at Pluto.
