The organization of the First Unitarian Society of Salt Lake City took place on the evening of Wednesday, 24 February 1891, in the parlors of the Walker House. The society chose its first board of trustees (nine members), which elected Nat M. Brigham as president, and forty-six people signed their names to a three-page constitution. Sunday services commenced the following Sunday in the Salt Lake Theater with Rev. David Utter speaking to audiences of from 300 to 400 people. The Sunday School was started the summer of 1891, and had a recorded enrollment of 113 six month later. In September this same year the Ladies Unitarian Society organized as a separate body "for the purpose of promoting the welfare of the Church, good fellowship, charitable and intellectual endeavors." Emily M. Almy was elected president. On 17 April 1893 the society was formally incorporated under the laws of the Territory of Utah.
