Frederick Bellinger (1904-1978) was born in New Orleans, Louisiana to Lyle Frederick Bellinger (1867-1952) and Annie Beall Dobbs (b. ?-1952). Lyle Frederick Bellinger was a career officer in the United States Army, serving as a Civil Engineer. As a result, the family often moved around the country and also lived in military installations in the Philippines, Japan, and Cuba. After his retirement from the military, Lyle Frederick Bellinger devoted a great deal of time to research of his genealogy and family history. He published three books about the Bellinger family line. His research files were passed to his son Frederick. Frederick Bellinger was born 14 August 1904. He was educated and received a degree in Engineering from Georgia Tech in 1926. In 1934 he began a graduate program. He completed a Masters of Science at Emory University and his doctorate at Yale by 1937. Also, during these years, he became an officer in the United States Army Reserves. With the beginning of World War II Frederick Bellinger was commissioned a Major in the United States Army as a Chief Chemical Engineer. Throughout the war his work focused on developing chemical propellants for rocket engines, an attempt to counteract the German “buzz bombs.” With the conclusion of the war, Frederick Bellinger left the Army, remaining in the reserves, and began teaching as an Assistant Professor at Georgia Tech. He remained at Georgia Tech until 1977. He retired just months before he died 22 October 1978. He had married Marie Parker in 1937 in Atlanta, GA. The couple had one daughter, Barbara Lynn, who was adopted by the Bellingers in 1947.
