Mary Kathleen Broderick was born on May 12, 1925 to Leo and Genevieve (Metcalf) Broderick. Her father was a state district judge and longtime attorney in Mandan. She was the fifth of six children born to the couple. Her siblings included Jane, William, John, Margie and Florence. Growing up in west central Mandan, much of her childhood play was in and around the Heart River. She attended St. Joseph's Elementary and graduated from MandanHigh School in 1944.
She relocated to the Twin Cities to attend the Minneapolis School of Art for 3 years focusing on oil painting. Upon graduation, she returned to Mandan and worked at the ND Highway Department while pursuing her art career on a part-time basis. Recognizing opportunities as an artist were limited in North Dakota, she moved to San Francisco. But successful female artists were an exception and not the rule in the late 1940s. She returned to Mandan after 18 months and worked for the ND State Tax Department. Her last venture from North Dakota was to Denver where she attended Regis College, but she returned to the state for good in December 1952.
After a temporary job as a substitute teacher, she joined the staff of Thomas W. Leach and his North American Royalties company. Thomas W. Leach, a surface geologist, did more than anyone to persuade the major oil companies to explore for oil in the Williston Basin.
Mary leveraged her ground-floor involvement in North Dakota's oil industry to secure a position with the Petroleum Information Service where she reported news items from the area. As her journalism skills flourished, so did her relationship with Steven H. Harris, a founding partner in the consulting geologist firm of Harris, Brown and Klemer, Inc. She subsequently worked for Sun Oil Company, performed record searches as a landman for the Pimco Oil Company of Wyoming and reserved as a reporter for The Rocky Mountain Oil Reporter for 9 years; before becoming a full-time homemaker and mother.
Mary and Steve were married in October 1955 and reared 5 children; Bruce, Steven B., Terry, Wayne and Diane. In between her other commitments, the couple traveled to worldwide destinations in support of Steve's geological career. But as their children moved on to their own pursuits, Mary turned her talents to community involvement and researching area historical events.
At the urging of Ernie Fleck, Mary purchased and restored the Stuart Dunlap Home at 201 7th Ave NW in Mandan. Constructed in 1904 by Stuart & Martha Dunlap, its original street address was 201 Mitchell Avenue. As one of her most notable projects, Mary led the effort to list the home in 1992 on the National Register of Historic Places. She has outfitted the home with Victorian period furniture and various souvenirs of her world-wide travels. Public tours of the home are held several times a year by the Mandan Historical Society.
During retirement, she continues to work on her golf game, although she has been unable to repeat her performance as the Lady Apple Tournament Golf Champion in 1964. In addition to her involvement as a charter and life member of the Mandan Historical Society and serving on its Board of Directors, she is active in her church and serves as a trustee to the State Historical Society of North Dakota Foundation. She currently resides in Bismarck.
