Robert McAlister
Walter Robert McAlister was a Canadian Pentecostal minister who founded the New Life Christian church in Brazil. In 1913 McAlister was the trigger point of the creation of Oneness Pentecostalism when he preached at a Pentecostal camp in Los Angeles that the "in the name of Jesus" baptismal formula was to be preferred over "in the name of the Father, the Son and the Holy Ghost". This led to a group, led by McAlister, Glenn Cook, and Frank Ewart rebaptizing themselves and forming what became the "Jesus only" or Oneness Pentecostal movement.
