Roswell Park was an American physician, best known for starting Gratwick Research Laboratory in 1898, which is now known as Roswell Park Cancer Institute. In 1900, the Gratwick family of Buffalo helped to finance Park's laboratory with a $25,000 donation in memory of William Henry Gratwick, a patient of Park's. Park was also a professor of surgery at the University at BuffaloMedical School and a surgeon at Buffalo General Hospital. When Park was thirty-one, he went to Buffalo, New York in 1883. He came from Chicago where he received his Doctor of Medicine degree from Northwestern University in 1876. He received his B.A. in 1872 and M.A. in 1875 from Racine College in Racine, Wisconsin. He then went on to finish his Doctor of Medicine studies at the Northwestern University School of Medicine in 1876. Park received an honorary M.A. from Harvard University in 1895 and an honorary LL.D. from Yale University. Over the years he served on many boards, both national and international. By 1914, the total number of textbooks, articles, and monographs that he wrote reached 167.
Buffalo was the host of the Pan-American Exposition in 1901. That year, President William McKinley was not even a year into his second term. He was staying in his summer home in Canton, Ohio when he left his summer home for the exposition fairgrounds. McKinley gave a speech at the Temple of Music on the Exposition grounds when Leon Czolgosz came from the crowd and shot McKinley twice at point-blank range. McKinley was taken to a hospital on the fairgrounds. It took nearly 40 minutes for the first surgeon to show up. Herman Mynter, a general surgeon from Buffalo, was the first to diagnose the president. Not long after Mynter's examination was finished, Matthew Derbyshire Mann arrived. After the two talked, it was agreed upon to perform the abdominal exploration. President McKinley agreed to the exploration. Work was done by Mann to try to find the bullet and treat the wounds. Efforts were made to contact Park, but he was in the middle of a neck dissection at Niagara FallsMemorial Hospital. As described years later by Park's son, the messenger ran into the operation room and told Park that he was needed immediately. Park is claimed to have replied "Don't you see, I can't leave. I am in the middle of a case even if it were for the President of the United States?"; the messenger replied, "Doctor, it is for the President of the United States." Park proceeded to finish the operation. Despite the importance of the situation, Park was only able to get to the exposition hospital via a train. The train engine and coal car were sent to Niagara Falls to pick him up and return to Buffalo, it held the record time between the two points at that time. The train was driven by Charles Meyers and was the only train allowed into the Pan Am. He was known after that as Pan American Charlie and died in 1934. Once Park arrived, Mann was about to close up McKinley and asked Park if there should be any placement of drains. Park told Mann that he was the best man to make that decision given the scenario. Mann decided not to drain the abdomen since there was no excess blood or fluid around to be drained. Park arranged for some nurses from the exposition to look over McKinley at the Milburn home until nurses from the army could arrive. Despite some promising results McKinley died in the Milburn home.
