In Kansas in 1923, Marguerite Graham became one of just 46 women attending Baker University. Initiated into Omicron chapter as a freshman, Marguerite was well known for her hosting abilities. Her mother, Mrs. A.L. Graham, became the house chaperone the following fall, at which time Marguerite was already acting as the chapter secretary. By 1924, Marguerite, who was very talented at tennis, had been elected the vice president of the Baker University Athletic Association.
After graduation, she served as a very active president of the Alpha Alpha (Chicago, Illinois) chapter, sponsoring carnivals, style shows, bazaars, dinner dances and bridge tournaments to raise money for the Cerebral Palsy Speech Clinic. Taking her hosting talent even further, she served as the transportation manager for the 1941 and 1949 Alpha Chi Omega conventions.
During 1943-44 while World War II was underway, Marguerite volunteered for the Red Cross in Australia and New Guinea. Her skills lied in finance, but due to her many talents she was asked to serve in intelligence, though she turned down the post. She met her husband, Captain Felix McWhirter, in Australia, where she also went nine months without a shower and celebrated Christmas with famed five-star General Douglas MacArthur. In 1945, Marguerite returned to Chicago and worked in insurance before taking three months to travel through seven different European countries.
Marguerite continued her dedication to Alpha Chi Omega by serving as province president from 1950-53, when she began splitting her time between Indianapolis and Phoenix. In 1955, she became the chair of the National Nominating Committee. Upon her death in 1988, Marguerite dedicated to Alpha Chi Omega $350,000, the largest gift ever received at that time, to be used to endow an alumnae assistance program named for her. Omicron chapter also received a gift of the same amount to be used for housing improvements, honoring Marguerite’s mother and her role as house chaperone.
