COOK, ARTHUR JAMES (1884-1931), English socialist and labour leader, was born at Wookey in Somerset, the son of a soldier. He was educated at the elementary schools and at the London Labour college, and worked as a miner in the pits, espe cially in the Rhondda area. In 1924, when Frank Hodges was made civil lord of the admiralty, he was elected, in his place, gen eral secretary of the Miners' Federation of Great Britain. He took a prominent part in the events leading up to the threatened general strike of 1925 and the actual strike of 1926, and the coal lockout of that year.
