Marion Moodie was not only an important figure in Calgary's history, but she also acted as an exceptional role model for women everywhere. In 1891, she arrived in Calgary where she studied medicine. After her graduation from the Calgary General Hospital in 1898, Moodie practiced medicine all over Alberta, wherever she was needed. This was especially true during World War I, when in 1916 she was made matron of Ogden Military Hospital in Calgary. Here, she contributed to the much needed force of medical staff during the war.

Not only was Marion Moodie a dedicated nurse, she was also a real nature-lover, with a huge affection for and connection with the visible aspects of the natural world. Moodie studied the flowers of Alberta, pressing and collected them. Eventually, she had created a collection of over 600 flora specimens for the Provincial Government. This collection was eventually added to the New York Botanical Gardens, the Smithsonian Institute, Harvard University and the Field Museum in Chicago.
