Helen L. Cannon (April 9, 1911 - October 20, 1996) was an American geologist specifying in geobotany and studying the effects of geological chemicals on the environment. She was a woman in science making large contributions to geology and advancements for in woman of science. She had a long lasting career at the United States Geological Survey in Washington, D.C. and Denver, Colorado soon becoming well known for her research and following discoveries. Cannon, along with two of her co-workers, set up and participated in the first organized unit studying chemicals in the real environment. The team concluded that by analyzing plants in a given area they could determine what metals were present in the soil and earth in that same area. In 1952, Cannon published a paper based on the findings and this paved the way for more research in geology and plants, geobotany. This research developed further into an important association with health and more specifically, cancer.[1] As an author, she has been largely collected by libraries.[2]
Early Life & Education
Helen Leighton Cannon was born in Wilkinsburg, Pennsylvania on April 29, 1911. As a young child she was encouraged by her father to observe the biodiversity along the Pennsylvanian countryside, which fostered her love for science and life.[1] Cannon enrolled in Cornell University for a degree in applied sciences, graduating in 1932. She remained involved in academics, participating in postgraduate work at Northwestern University before enrolling for a Master’s of Science degree from Pittsburgh University. Cannon received her M.S in geology in 1934 and continued research in academics before joining a staff of geologists working for the Gulf Oil Company in 1935.
Career
Once Cannon finished her degree in applied science at Cornell University, New York, in 1932 she continued to attend many more Universities for post graduate work in geology until 1935 when she got her first job at in Saginaw, Michigan at Gulf Oil Company. After spending three years with this company Cannon moved again, first to Washington, D.C., and then to Denver, Colorado. Here she set roots and began her life-long career at the U.S. Geological Survey. Cannon was the third woman to work for the company and dedicated her entire career to doing research for them.[1]
Contributions to Geography
During her career as a scientist Helen L. Cannon focused on the health effect that geochemical environments had, as well as geobotany. Cannon worked on many pieces in these subjects. One of works was on the method of using indicator plants to determine where uranium deposits might be. Hardier indicator plants that could withstand being in an environment with uranium were used to find out which locations were more likely to contain uranium in the ground. Uranium in an area could also be determined by looking at the chemical make up of certain plants to try at detect certain elements. This helped find new locations of uranium, specifically focusing on the Colorado Plateau.[3][4]
Death
Helen L. Cannon died on October 20 in 1996 at the age of 93. She past away in her Santa Fe, Mexico home.[1]
Awards and Honors
Helen has received numerous awards and honors in her lifetime, including becoming the first woman in an all men's science group to have a membership. This group was known as American Men in Science and was an important event that other American women and men respected. Besides the American Men in Science Cannon also attained memberships in Geological Society of America, Geology and Public Policy Committee, American Association for the Advancement of Science, Association of Exploration Geochemists and the Society of Environmental Geochemistry.[1] In 1970 the Department of Interior awarded Cannon the Meritorious Service award and five years later she received the topmost award known as the Distinguished Service Award from her continuous work at the Department of Interior. With Cannon's discoveries relating trace elements affecting health she became associated with the National Research Council and was given subcommittee chair on the Geochemical Environment in Relation to Health and Disease.[1]
