In 1908, Alpha Kappa Alpha Sorority was founded on the campus of Howard University. The founders are Anna Easter Brown, Beulah Burke, Lillie Burke, Marjorie Hill, Margaret Flagg Holmes, Ethel Hedgeman Lyle, Lavinia Norman, Lucy Slowe, Marie Woolfolk Taylor, Joanna Berry Shields, Norma Boyd, Julia Brooks, Ethel Jones Mowbray, Nellie Quander, Nellie Pratt Russell, and Minnie Smith.
       
The founders had a vision of lifelong sisterhood that still continues to be demonstrated by the sorority's members 111 years later.  Though made for college-trained women, Alpha Kappa Alpha has a legacy that extends beyond graduation. The goals of its program activities center on significant issues in families, communities, government halls, and world assembly chambers. Its efforts constitute a priceless part of the global experience in the 21st century.

Iota Sigma has been an active force in the community, with service events like Hoop for the Cause, Christmas Krafts for Kids, and Total Body Takeover week. Each member in the chapter serves the community regularly two or more times each week on their own time.
