The timeline

1890 to 2002

Every entry below is sourced, and three of them are disputed, which the entries say on their face. A timeline that hides its uncertain dates is asking to be trusted rather than checked. This one prints cleanly if you need it on paper.

    Disputed. Some references say 1932. Thirteen two-year terms ending in 1961 back-date to 1935, elected late 1934; we follow the arithmetic and would like the state archives to settle it.

The Olympic record, in full

Three Games, five medals. He was an alternate in 1928 and again in 1932, at forty-two, and competed in neither. He was not on the 1924 relay. Claims of six medals or four Games are wrong.
