Randolph Caldecott
Randolph Caldecott (; 22 March 1846 – 12 February 1886) was an English artist and illustrator, born in Chester. The Caldecott Medal was named in his honour. He exercised his art chiefly in book illustrations. His abilities as an artist were promptly and generously recognised by the Royal Academy. Caldecott greatly influenced illustration of children's books during the nineteenth century. Two books illustrated by him, priced at a shilling each, were published every Christmas for eight years.
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.
