Tanox

Tanox was a biopharmaceutical company based in Houston, Texas. The company was founded by two biomedical research scientists, Nancy T. Chang and Tse Wen Chang in March 1986 with $250,000, which was a large part of their family savings at that time. The two Changs had been research managers working with a range of monoclonal antibody projects in Centocor, Inc. based in Malvern, Pennsylvania from 1981 to 1985. The Changs were recruited by Baylor College of Medicine toward the end of 1985 and offered faculty positions in the Division of Molecular Virology. Soon after their arrival, they were encouraged by a high-ranking Baylor official and local business leaders to start a biotech venture in Houston. This was in a period of time when the economy of Houston was in slump as the result of the collapse of the oil industry.
