In 1868 he became lecturer on morbid anatomy in the same institution, and in 1870 lecturer on clinical medicine. From 1876 to 1887 he was professor of clinical medicine, and in 1887 succeeded Dr Alfred Still as professor of theory and practice of medicine.
He was elected provost of the university in 1881, resigning that position in 1894. For his services as medical director of the Centennial Exhibition in 1876 be was made knight commander of St Olaf by the king of Sweden. He founded the Philadelphia Medical Times, and was editor of that journal in 1870-1871. He was known particularly for his contributions on the subject of the theory and practice of medicine, and the System of Medicine which he edited in 1885-1886 became one of the standard textbooks in America. He died on the 28th of July 1898 at Pleasanton, California.
Among his contributions to the medical and scientific journals of the day, were:
Dear Sir:--In accordance with the enclosed resolution unanimously passed at a meeting of the Dr. Pepper Testimonial Committee the undersigned were appointed by the chairman to apply to you for the assignment of the site on the Campus whereon to erect a br onze statue of Dr. Pepper by the Sculptor, Karl Bitter.
The difficulty met with in obtaining sittings from Dr. Pepper caused serious delay in the completion of the statue, and it was only in 1896 that it was finally accepted by the committee in charge, after it had been critically, though unofficially, examine d by Mr.
WILLIAMPEPPER, M. On one side is inserted a fine bronze panel, representing a draped figure sitting with calm dignity, under the spread-out foliage of a tree, holding in her hand the Torch of Knowledge.
Pepper recounts the days King spent in Memphis organizing the sanitation workers, lobbying The Invaders (a young, fl militant group) to join the peaceful movement, and preaching his last sermon at the Mason Temple.
Pepper is at full strength when he characterizes the fearful, dejected atmosphere across the country after news spread of King's murder.
Pepper's account of the months Ray spent in limbo, traveling across the country at the direction of a shadowy figure dubbed "Raul," is reminiscent of film noir movies where the lead is caught in a web of deceit beyond his comprehension.
