A strong advocate for cultural preservation, Blue and his mother, Margaret George Brown, were the last known native speakers of the Catawba language.
Blue first entered politics in 1905 when he was made a member of the interim governing council of the tribe along with Lewis Gordon and Ben T. Harris.
Native Americans like Blue were functionally treated as non-citizens in the 1930s - leading to the second citizenship petition.
Blue made regular trips to Columbia, South Carolina where he would speak to the state legislature on behalf of the interests of the Catawba.
Blue was also a key figure in the process of the Catawba gaining federal recognition which was completed in 1941.
He also was one of the main advocates of the Catawba accepting termination of federal wardship in at the time of his death.
Initially raised in the Catawba traditional beliefs,[5] on May 7, 1897, Blue was also baptized into the Church of Jesus Christ of Latter-day Saints in South Carolina.
