[1] In the early years of the Institute of Religion at the University of Utah, attendance was growing and some male students wanted a way to build their brotherhood with fellow Latter-day Saints.

Shortly afterward, these houses were collectively named Lambda Delta Sigma, which would be a co-educational Greek society open to anyone willing to uphold Latter-day Saint ideals.

[3] Elaine Cannon, Winnifred Jardine, Frank Bradshaw and Alfred Nielsen were called by the general authorities to make plans for a new LDS sorority and divided the organization, making Lambda Delta Sigma a sorority and creating Sigma Gamma Chi as its fraternity.

In 1977, the sorority was transferred to the leadership of the Relief Society General Presidency and the national LDS President served on the General Relief Society Board and by 1982, all Lambda Delta Sigma officers gained National Board positions.

In June 2000 it was announced that in September, the sorority was to absorbed by the Institute Women's Association, a church organization for all female Young Single Adults.
