Isabel Kline Rock grew up in Jersey City, New Jersey. She enrolled at Goucher College where she followed in her sister’s footsteps. Her older sister was a Gamma Phi Beta at Goucher and the biological sisters became sorority sisters. In addition to being president of her sorority chapter, she was treasurer of the senior class of 1912. She majored in English and Sociology.
Three years later, in 1915, she married architect P. Arthur Rock. The couple had two sons.
Rock was a visitor to the 1917 Gamma Phi convention which was held in Baltimore.
The Rock family moved to Connecticut in 1936. Isabel Rock immersed herself in civic and community activities. Among the organizations which benefited from her leadership were AAUW, Red Cross, Community Chest, Family Service Bureau, League of Women Voters and the Mental Health Society. She was also active in the Daughters of the American Revolution.
She was elected to the Connecticut State Assembly in 1961 and served until 1969. Rock was a charter member of the National Society of State Legislators.
In a talk to the Douglass College alumnae in 1961, Rock said:
One of the joys of living a long life is the satisfaction of seeing dreams come true. Never stifle a new thought nor a good intention. Test its soundness, then give it all your enthusiasm and your energy. You will find miracles happening all around you.
She died October 1, 1971.
