Dr. Octavio Garcia, 94, who paved the way in south Texas for Hispanic doctors, died Thursday at his daughter's home in Massachusetts. The Mier, Mexico, native attended medical school in St. Louis and won a fellowship in pathology and bacteriology. But when he arrived in Texas in 1930, McAllen Municipal Hospital denied him privileges. Later, a change in administration opened the door for Dr. Garcia to become the first Mexican physician to practice there. The Ku Klux Klan sent him threatening letters, but he continued to practice and won over the community. He retired in 1980.
