Frederic G. Melcher
Melcher proposed the Caldecott Medal in 1937 to honor children's picture books. Named for British illustrator Randolph Caldecott, the medal is presented annually for the "most distinguished picture book for children".
Caldecott Tunnel
The east-west tunnel is signed as a part of State Route 24 and connects Oakland to central Contra Costa County. It is named after Thomas E. Caldecott (1878–1951), from 1930–1932, member of the Alameda County Board of Supervisors 1933-1945, and president of Joint Highway District 13, which built the first two bores.
