Pioneering businessman. Known as "Mr. Insurance", a leader in the Atlanta insurance industry and community activities for more than 50 years. In 1931 created Alexander & Co (with $100 in savings), an Atlanta insurance brokerage firm that eventually became the oldest black firm in the city and one of the most successful. He managed Alexander & Co for nearly 60 years and had a roster of clients including Coca-Cola, and the City of Atlanta. He later established the Southeastern Fidelity Fire and Casualty Company in 1951 and served as Executive Vice President and Managing Officer until the company was prematurely sold in 1967. Southeastern Fidelity Company provided more than $50,000,000 of property protection for its client groups, and was the first Black-owned multi-line insurance company. Recognizing the absence of Black representation in electoral politics in both the City of Atlanta and the State of Georgia for more than 90 years, Alexander embarked upon an ambitious effort and ran for the office of City Alderman in 1957 and for the State Senate in 1961. Although unsuccessful in each of these bids, his actions provided the motivation for other Blacks to become involved in seeking election of public office, thus paving the foundation for not only the first elected Mayor of the City of Atlanta, but also for numerous other elected positions throughout the South. In addition to serving as the President of his insurance agency, he served as an Adjunct Professor of Insurance at Howard University, Washington, D.C., the boards of Morehouse College and the Atlanta University Center. In 1970, he was awarded an Honorary Doctor of Laws degree by Morehouse. Over the years, he has remained a pillar of the community and has assisted numerous other Blacks in gaining responsible positions in both the private and public sectors. Alexander also was an active participant in many professional and other organizations. He was preceded in death by his first wife Dorothy and a son T.M. Alexander, Jr. Alexander died at age 92.
