English meteorologist and climatologist Hubert Horace Lamb (1913–1997), who founded the Climatic Research Unit at the University of East Anglia in 1971, is considered by many to be the greatest climatologist of the twentieth century. He began his career as a weather forecaster for the Irish Meteorological Office and later was with the British Meteorological Office. While there, he participated in a Norwegian whaling expedition in Antarctica from 1946 to 1947. It was during this time in Antarctica that he began to study how the world’s climate must have changed, and he pursued this subject after joining the Climatology Division of Britain’s Meteorological Office in 1954. Using records there, he researched and published papers and books about how Great Britain’s climate had changed noticeably since the middle of the nineteenth century.
