Gerard Roland Vela, microbiologist, professor, author, and community leader, son of Marcial Vela Bermea and Maria Guadalupe Múzquiz de la Garza, was born in Eagle Pass, Texas, on September 18, 1927. He was a descendant of Spanish settlers who arrived in San Antonio around 1719 (maternal) and the Rio Grande Valley around 1740 (paternal). He was bilingual and bicultural. Vela spent his early childhood in Crystal City, Texas, until he was about eight years old and his family relocated to San Antonio. He attended Stephen F. Austin Elementary School and San Antonio Vocational and Technical High School (known as Fox Tech High School) until April 1945, when he left high school and enlisted in the United States Navy. While in the navy, he studied for and obtained his GED. After the end of World War II Vela was honorably discharged in July 1946. He returned to San Antonio and enrolled in San Antonio Junior College (present-day San Antonio College). In 1947 he transferred to the University of Texas at Austin, where he received his bachelor of arts with a major in bacteriology and a minor in chemistry in 1950. In 1951 he received his master of arts in the same disciplines.
On September 20, 1953, Vela married Emma Lamar Codina Longoria of Mission, Texas. They had four children: Gerard Jr., Anna Maria, Yolanda Marta, and Jaime Joel. Vela worked on hormone research at Southwest Foundation for Research and Education (see TEXAS BIOMEDICAL RESEARCH INSTITUTE) in San Antonio before he received a fellowship in the biochemistry department at the Harvard School of Medicine in 1955. Vela and his growing family lived in Boston, while he worked as a bacteriology technician at Harvard. He also worked in the school of public health and took courses in chemical engineering. In 1957 he returned to San Antonio and worked as a clinical chemist at Santa Rosa Hospital. Vela returned to the University of Texas in 1960 and received a doctorate in microbiology with a minor in biochemistry in 1963. He entered the Civil Service in 1963, then worked at Brooks Air Force Base until 1965, when he left to assume a teaching and research position at North Texas State University (now the University of North Texas) in Denton, Texas, where he became the university’s first Latino professor to achieve tenure. He retired in 2000 and remained in an emeritus position until 2002.
During his tenure at North Texas, Vela supervised forty-four master's and twenty doctoral students. He also published and co-authored seventy-five research papers and presented more than 100 research reports at international, national, regional, and state scientific societies. He served as Associate Dean of the College of Arts and Sciences for five years. In addition, he was invited to teach courses in microbiology at various universities in Mexico, Venezuela, Colombia, Argentina, Uruguay, Spain, and Thailand. He also taught courses at the University of Texas at Austin for a series of summers. His involvement in academic life was evidenced by the large number of professional societies, both nationally and internationally, in which he was involved, most notably the American Society for Microbiology, and in 1975 he was elected to its American Academy of Microbiology. He edited the newsletter of the Texas chapter of the American Society for Microbiology. In 1999 he was recognized for his discovery of a new nitrogen-fixing bacterium, Paenibacillus velaei, which was named in his honor. Additionally, Vela consulted with various companies, including Frito-Lay and Campbell Soup Company, regarding microorganisms, and he edited the Texas Journal of Science for approximately eight years.
As committed as Vela was to the advancement of science, he was equally committed to his involvement in community service. In 1979 he was the first Hispanic to be elected and serve on the Denton City Council. From 1980 to 1991 he served on the board of the Texas Municipal Power Agency. He helped found the Firehouse Theater Group and was active in the Denton County Cooperative Agency. He also served as secretary of the Denton Forum, as a board member for Our Daily Bread, and on the Traffic and Safety Commission. Vela was a licensed pilot and served as chairman of the Municipal Airport Board in Denton. On a national level, he served on committees for the National Science Foundation, the National Institutes of Health, the Environmental Protection Agency, the Department of Education, and the Howard Hughes Medical Institute. In 2000 the Millennium edition of Latino Monthly magazine credited Vela as being one of the “Outstanding 100 Texas Latinos of the Twentieth Century.” In 2019 the G. Roland Vela Athletic Soccer Complex in Denton was named after him. Vela spent his life working to promote education to young people.
Vela authored two textbooks, Practical Microbiology for the Food Professions (1989) and Applied Food Microbiology (1997), and two historical biographies, The Men Named Antonio López de Santa Anna (2003) and Bernardo de Gálvez: Spanish Hero of the American Revolution (2006). As a member of the Granaderos de Gálvez, he traveled with the group to the birthplace of Bernardo de Gálvez in Spain. In full regalia, he presented a copy of his book on Bernardo Gálvez to Prince Felipe VI of Spain (now King Felipe VI). Gerard Roland Vela was a Catholic. He died at the age of ninety-three at his home in Denton on January 26, 2021. He is buried at Roselawn Memorial Park.
