Dr. Ferdinand Hasbrouck, a New York oral surgeon and an 1870 graduate of the University of Pennsylvania School of Dental Medicine was among the first practitioners to succeed in the regular and commercial use of anesthesia in private surgical practice. In 1893, U.S. President Grover Cleveland was diagnosed with an intraoral tumor. The President chose Dr. Hasbrouck to serve among his team of surgeons and simultaneously as "the" anesthesiologist for the procedure. For political reasons, Cleveland did not want the public to know about his condition. The procedure was a milestone for the practice of anesthesia. Ferdinand Hasbrouck's son, James F. Hasbrouck, discussed below, was among the founders of the Columbia University College of Dental and Oral Surgeons in 1916.
