More about this marker. As recalled in Link 2 below, the "Guthrie Boulder" was brought to Chicago by Samuel Guthries grandson, Ossian Guthrie, a noted geologist who discovered the boulder in Worth, Illinois, and sought to use it to commemorate his father, the first manufacturer of chloroform. After a series of disputes and legal cases between the Chicago Medical Society and the South Parks Commission, the boulder was placed in Grant Park, near the Art Institute, around 1905. A few years after Ossian Guthrie died in 1908, the South Parks Commission moved the stonewhich still did not have an engravingto Washington Park on the south side. A plaque was finally added in 1925, but later stolen; in 1933, an engraving was added. Finally, the stone was sent to its final resting place, near Cook County Hospital and Presbyterian-St. Lukes Hospital. A dedication ceremony involving Dr. Guthries descendants took place on May 19, 1957.
Regarding Samuel Guthrie, M.D.. Samuel Guthrie was a physician who served in the War of 1812 as an Army surgeon. In 1831 he was the first to publish findings on the discovery of chloroform, an anesthetic that enabled better treatment during surgery and childbirth, and in war during amputations. Guthrie's son, Alfred, settled in Chicago in the 1840s and died here in the 1880s.
