In late April, the CBS program ?60 Minutes? aired an extraordinary report titled ?Saving the Children,? about Sir Nicholas Winton, a 104-year-old (now 105 ? his birthday was May 19) Englishman who in 1939 helped 669 children, mostly Jews, escape Nazi persecution in Czechoslovakia through a program called Kindertransports. Renata Laxova was one of those kids. Laxova, 82, is an emeritus professor of genetics at UW-Madison.
