Professor T. C. Hsu, (17 April 1917 – 9 July 2003), was a cell biologist. He was born Tao-Chiuh Hsu in Shaoxing, Zhejiang, China. He determined the accurate haploid chromosome number of Homo sapiens and characterized the human karyotype.

He worked in the laboratory of Charles Pomerat at UTMB in the early 50s where he discovered an improved method of preparing chromosomes that led to the accurate identification of 23 pairs of chromosomes in human somatic cells. He was president of the American Society for Cell Biology and served on faculty at M.D. Anderson for more than 30 years. He was a UTMB GSBS Distinguished Alumnus Award recipient in 1996.
