Missionary in Mexico
c. 1898
Pratt was one of the first missionaries to Mexico, and in 1876 at Hermosillo, Sonora, Pratt and Meliton Trejo performed the first baptisms recorded by the LDS Church in that country. Pratt was later president of the Mexican Mission based in Mexico City from 1884 to 1887. He succeeded Anthony W. Ivins in this position and was succeeded by Horace S. Cummings. After his release he moved to Colonia Dublán in Nuevo Casas Grandes, Chihuahua. He also for a time owned and resided at the Cliff Ranch outside Cave Valley, Chihuahua. In 1895, when the Juarez Stake was organized in Mexico, Pratt, along with Henry Eyring, was called to serve as one of President Ivins' counselors, a post he held until 1908 when the stake was reorganized with Pratt's son Junius as president.
