"Founded in 1824, Jefferson Medical College, now the Sidney Kimmel Medical College, has awarded more than 31,000 medical degrees and has more living graduates than any other private medical school in the nation. It offers both undergraduate medical education programs and innovative joint degree programs to more than 1,000 students each year." (college website)
Dr. Robert E. Rogers had a 25 year career in Chemistry at University of Pennsylvannia before moving to Jefferson. "The long and distinguished service of Dr. R. E. ·Rogers as teacher of chemistry came to a close by his decease in 1885. Excelling in the art of illustration by striking experiments, the exposition of his difficult science lacked nothing for clearness of speech, while his delivery was always agreeable."
