Byrd, Richard Evelyn
In 1930 Byrd was promoted to rear admiral, and his book Little America was published. His second large expedition was organized in 1933, and headquarters were established once again at Little America. As winter approached, he set up an advance base 123 mi (198 km) closer to the South Pole and stayed there alone for several months making observations. Discovery (1935) and Alone (1938) were records of this fruitful expedition. In 1939?40 he was again in the antarctic, commanding a government expedition, and in 1946?47 he headed the U.S. navy expedition, the largest yet sent to the region (see Antarctica). In 1955, Byrd was placed in command of all U.S. antarctic activities, and in 1955?56 he led his fifth expedition to the region. Due mainly to his efforts, the U.S. navy organized (1955?59) Operation Deep Freeze.
