Artist, Medical Equipment Inventor. She is remembered for being an American artist in the first half of the 20th century. Leaving Chicago, Illinois, she traveled to Paris, France to become a student of Mary Cassatt and part of the Alice Woods Ullman and Gertrude Stein's artists circle. While she was in Paris, World War I began and she laid aside her paint brush to become in charge of the surgical supplies of the American Ambulance Hospital in Newully-sur-Siene. In 1916 she became the director of the Franco-American Corrective Surgical Committee. After seeing soldiers with the serious battle wounds of their limbs, she, along with orthopedic surgeons, designed an inexpensive wooden apparatus with weights and rope to maintain limb alignment by traction while healing. Her knowledge of the human anatomy from art school helped her in this task. Not only did the device help in healing but it was documented to decrease limb amputation. The device was named the “Gassett Suspenory Hammock” and was a pioneer device of modern-day orthopedic traction. She published articles in medical journals about her device and the outcomes of using it. For her work, she was decorated in June of 1917 with France's highest honor, the Cross of the Legion of Honor. Although there have been many American women receiving this honor, she was the second woman with the first being writer, Edith Wharton. She received the Medaille of d'Honneur from France for her twenty-six months of continuous service in the American Ambulance Hospital and other honors from the French government. After the war, she remained in France to teach and do portrait paintings for a total of twenty years. She wrote two healthcare books, which are still in print, in the French language, “La Cle” in 1938 and “La Sante” in 1950. Although she had little to offer, she was a consultant for the treatment of United States President Franklin Roosevelt in his last months of life. In her later years, she returned to the United States. She can be considered as a successful artist with her 1907 piece, “Portrait of a Lady,” being in a 2018 auction at Sotheby's in New York and the portrait sold for $4,000. Her darker piece, “Portrait of a Woman with a Dog,” sold in 2017 at Skinner's Auction for $500. At the Smithsonian Institution, Bennett Harvey's scrapbook is on display containing newspaper articles about Gassett's work during World War I, pamphlets for fund raising, and letters from her to the editor of the “Chicago Journal.” All of the funding for her work during World War I was obtained from American citizens. In the book “Modern Hospitals” volume 9, the article, “An Artist's Works in War Orthopedics,” tells how she raised funds for her hospitals in France. In 1898 she was one of the founders of the Women's Athletic Club of Chicago.
