Edward Weaver Moore, Texas state legislator, was born in Henderson, Texas, on March 13, 1901, the son of Judge William Wright and Matilda (Weaver) Moore. He was descended from several generations of jurists and lawyers. Moore received his LL.B. from the University of Texas and was an assistant attorney general from 1925 to 1927. On October 3, 1928, he married Helen Paxton, sister-in-law of Governor Dan Moody, in the Governor's Mansion at Austin. They had one child.
In 1933 Moore was elected as a Democrat to the Texas House of Representatives; he served one term before serving as senator from Harris County from 1935 to 1947. During his tenure in the Senate he was chairman of the State Affairs Committee and, in 1939, president pro tem. He wrote the "white primary" bill of 1945. In 1946 he was at the center of a controversy over the constitutionality of a special independent session of the Texas Senate. He was offered appointments by Governor Allen Shivers as secretary of state, land commissioner, and justice of the state Supreme Court but declined each of them. In the late 1960s he became state chairman of the American Independent party, led by Alabama governor George Wallace. Moore died in Houston on May 9, 1971.
