The first people to complete the then-known contiguous US 14ers (51 CO, 12 CA?, 1 WA?) were father and son Carl and Bob Melzer in 1939. Bob was 11 years old at the time of completion (Roof of the Rockies).
The only two people I know of that have summited all of the ranked peaks on this list are Bob Packard and Brian Kalet.

The List

Ranked peaks have at least 300 feet of prominence.
