Education

Penrose completed a physics degree at Harvard with highest honors in 1881, graduating at age 19, two months after his mother died of tuberculosis. He wanted to pursue a medical degree at the University of Pennsylvania concurrently with a Ph.D. in physics at Harvard. The schools worked out an arrangement that involved Penrose's traveling to Harvard for two months out of each year. At Harvard, Penrose studied under physicist John Trowbridge, who was known for his work in electricity and magnetism. In volume 17 of the ''

'' (1881–82), Penrose published two papers: "Thermo-electricity – Peltier and Thomson effects" and "Thermo-electric line of copper and nickel below 0°". His physics PhD thesis was titled "The mathematical theory of thermoelectricity and the relation between thermoelectricity and superficial energy". Penrose graduated from both programs in 1884 at age 22. He finished medical school one year behind Amos W. Barber; the two became friends there, and Barber later became the acting governor of Wyoming. After completing the doctorates, Penrose turned his attention away from physics and toward the practice of medicine. Penrose was a resident at

Career

Penrose remained in Philadelphia after his residency, having been hired as an attending outpatient surgeon at Pennsylvania Hospital. After contracting tuberculosis in 1891, Penrose left his Philadelphia medical practice. On the advice of Amos Barber, who was by then the acting governor of Wyoming, Penrose came to that state, and Barber had him put up at the Cheyenne Club, one of the wealthiest and most exclusive establishments on the frontier. Penrose placed himself on a regimen of physical activity; he dug with a pick and shovel in the morning and rode horses in the afternoon. By early the next year, he had gained Returning to Philadelphia, Penrose was hired as Professor of Gynecology for the medical school at the University of Pennsylvania in 1893, succeeding William Goodell.Leach, p. 122. He authored the ''Text-Book on Diseases of Women'' (1897), which the '' Cincinnati Lancet-Clinic'' described as a concise text that was well-suited for

The lab conducted important research into the prevention of tuberculosis and studied the impact of diet on animal fertility and on the richness of animal coats. While working at the Penrose Research Laboratory, Corson-White developed "Zoo Cake", which became a popular nutritional product for zoo animals. In the foreword to Fox's ''Disease in Captive Wild Mammals and Birds'' (1923), he decried the fact that most animal diseases were poorly understood, especially relative to the progress that had been made in human medicine. Fox's book is dedicated to Penrose. In 1911, Penrose was named a Fellow of the American Association for the Advancement of Science; he belonged to several sections of the organization. He served as the president of the Zoological Society of Philadelphia from 1909 until his death. A well-respected conservationist, he also spent many years as president of the Pennsylvania Fish and Game Commission.


Contributions as a surgeon


Penrose drain

In the late 19th century, surgeons were divided on whether drainage tubes should be used frequently or infrequently in abdominal surgery. Penrose was an advocate of the maxim "When in doubt, drain." He made a presentation on the topic before the

or other tissues upon drain removal. In 1890, Penrose designed a rubber drain made of a condom with its tip cut off. The Penrose drain became the dominant surgical drain until suction drainage was introduced in the 1950s.


Gynecean Hospital

Penrose and his father participated in the founding of the Gynecean Hospital, which opened in January 1888 as the first hospital in Philadelphia that was exclusively for women. Penrose served as the hospital's chief surgeon, and his father was its president. The hospital was run out of a small home on Cherry Street until it moved to a home near the intersection of Hamilton Street and 18th Street on April 1. The hospital was permanently established at 247 N. 18th Street in 1891. Penrose and Joseph Price served as attending surgeons until late 1890, when Price resigned and was replaced by David Hayes Agnew. In 1901, the hospital attracted criticism from ''

The hospital was criticized because it had received $175,000 since 1889, because it was impossible to tell whether the hospital ever treated poor patients, and because Penrose's brother was a senator. Penrose remained associated with the Gynecean Hospital for life. By 1924, as chairman of the hospital's board of directors, Penrose recommended that the facility be abandoned because it was only filled to ten percent of its capacity. The following year, Gynecean Hospital merged with the

Johnson County War

While he was at the Cheyenne Club recovering from tuberculosis, Penrose agreed to serve as the surgeon on an invasion led by a group of cattlemen, the

, whose most well-known work was '' The Virginian'', a fictionalized version of the events of the Johnson County War. Penrose wrote a letter to Wister during the conflict, and in doing so, he may have inspired the most well-known line in ''The Virginian'' ("You son-of-a--"). He had written in his letter that "during the last two months 'son of a bitch' has been a favorite expression in this country. Wyoming is in the son of a bitch stage of her civilization and could not get on any more without it than she could without a lariat and a branding iron." When two alleged cattle rustlers, Nate Champion and Nick Ray, were ambushed and killed by a group of the cattlemen, Penrose was among the suspects arrested. He was taken to Douglas, Wyoming, where lynching was briefly considered. Governor Barber, who had also been a longtime friend of the cattlemen, intervened; he had Penrose brought back to the Cheyenne Club by a

''. Penrose was ultimately cleared of responsibility in the attack. In 1914, Penrose wrote a memoir, ''The Rustler Business'', about the events in Wyoming. Author John W. Davis wrote that Penrose's account is especially valuable because Penrose was not entirely familiar with the official opinions held by the group of cattlemen. Penrose parroted some of the myths that were widely held by the group, such as the thought that Cattle Kate needed to be killed in the interests of the country. However, Penrose also expressed ideas that differed from those held by the men of the WSGA, such as the admission that the cattleman invaders had started north with the goal of targeting 70 specific people, including Nate Champion.
