Aurelia Read Spencer Rogers (October 4, 1834 – August 19, 1922) was the founder of Primary, the children's organization and official auxiliary of the Church of Jesus Christ of Latter-day Saints.
As the second eldest child, Aurelia and her elder sister were made responsible for assisting the other four siblings in the move to the Salt Lake Valley, which the Spencer children completed in 1848.
While praying for guidance, Rogers said she heard a voice say "that there was an auxiliary organization [in the church] for all ages except the children".
With the assistance of general Relief Society president Eliza R. Snow, Rogers organized a Primary Association for her local Farmington ward on August 11, 1878.
That same year, she was a delegate to the meeting of Susan B. Anthony's National Council of Women in Washington, D.C. Rogers died in Farmington, Utah at the age of 87.
