The final years of Pratt's life were busy, and the constant traveling gradually wore him down. Just after the April 1931 General Conference, Pratt stayed in Salt Lake City to undergo a hernia operation. While recovering in the hospital, Pratt experienced complications. His condition quickly deteriorated, and he died on 14 April 1931. He left behind his wife and ten living children. On 17 April, hundreds of people filled the Assembly Hall on Temple Square for Pratt's funeral. Grant and other general authorities spoke at the service. They expressed regret that Pratt had not lived to see the church grow large in Mexico.
