The Lambda Chapter was chartered in 1921 at The University of Chicago by seven outstanding women, including two of our beloved Founders:

​

• Osceola Macarthy Adams, First President of Lambda Chapter

• Marguerite Young Alexander

• Freddie Billings (Beta Chapter)

• Marie Ody Cobb (Beta Chapter)

• Margaret Watkins Hardiman (Beta Chapter)

• Vivian Mason (Alpha Chapter)

• Ruby Martin Payne (Beta Chapter)

​

Among the first initiates were Sorors:

​

• Estelle Webster MacNeal

• Tillie Houston White

• Sophia Boaz

​

Today, Lambda is known as the undergraduate Chicago-Citywide Chapter; home to not only The University of Chicago, but also University of Illinois-Chicago, Chicago State University, Illinois Institute of Technology, Loyola University, Roosevelt University, and Northeastern Illinois University.
