Yesterday, May 17, was a special day in my family. My late mother, Melva Sparks Bidlack, was born on that day, a century ago. We lost her to cancer in the 1990s, but like most dutiful sons, I still miss her, and I find it almost hard to believe that she’d be 100 today. She was born on a farm in remote Clio, Iowa. That long-ago May would also see the birth of perhaps America’s greatest mind, physicist Richard Feynman. The year would end with great hope, when the War to End All Wars concluded on Nov. 11.
