### Summary

 Guillory works in functional analyis, especially Douglas algebras. "I learned a lot of mathematics, and put it in the perspective that I needed to continue in this field," he continues. "I still get help from my colleagues at Berkeley. Eventually, I hope to write a book about Douglas algebras."

### Biography

 birth place: Church Point, Louisiana   Guillory was an undergraduate at Southern University in Baton Rouge where his biggest problem involved writing English and mathematics. "My parents spoke Creole (a dialect of French)," he explains. "I did not have much trouble reading, but writing was difficult." After earning a B.S.from Southern University (1969), his teacher, Rogers Newman urged him to go to graduate school. He earned an M.S. (1974) and a Ph.D. (1978) from the University of California at Berkeley After earning his doctorate, he got a faculty position at Louisiana State University the University of Louisiana at Lafayette (originally Southerestern Louisiana Universitynear where he was born and raised. A [National Science Foundation] M[inority] R[esearch] I[nitiation] award enabled him to take time off from teaching and return to a research setting at UC-Berkeley. "It was a personal dream come true," he comments. "Without the grant, I never would have come near my potential." Guillory works in functional analyis, especially Douglas algebras. "I learned a lot of mathematics, and put it in the perspective that I needed to continue in this field," he continues. "I still get help from my colleagues at Berkeley. Eventually, I hope to write a book about Douglas algebras." Guillory was dedicated to his research, but always found time for his students. He was a very popular teacher. Periodically, Dr. Guillory went back to Southern University to encourage other minorities to become mathematicians and scientists. "Things are wide open for minorities," he states, "but not many of them are interested in these careers. We must get young people to realize that the opportunities can be limitless. This is especially true in mathematics where there are so few minorities. If we can get more to participate in mathematics and science, I believe minorities have much to contribute." Guillory put his family first, and his church not far afterwards. Dr. Guillory died suddenly March 18, 2001. He was 55 years old.   Research Guillory works in functional analyis, especially Douglas algebras. "I learned a lot of mathematics, and put it in the perspective that I needed to continue in this field," he continues. "I still get help from my colleagues at Berkeley. Eventually, I hope to write a book about Douglas algebras." 10. Guillory, Carroll; Li, Kin Y. Algebras of Blaschke products unimodular on trivial parts.
