James Ewing, 1866-1943, first described the tumor that was to be named after him in the 1920's. It was Ewing's
work which established that the disease was separate from Lymphoma and other types of cancer know at the
time. Ewing was born in Pittsburgh and embarked on his medical career in 1888. In 1889 he was appointed as
the first Professor of Pathology at Cornell University where he developed a keen interest in cancer. He was a
co-founder of both the American Association for Cancer Research in 1907 and the American Cancer Society in
1913. He was also a pioneer in the use of radiotherapy in the treatment of cancer.
