Early life and education
Dyckman was born to Louise (Heroy) Dyckmam and Francis Henry Dyckman, a banker and miller, in Sleepy Eye, Minnesota on August 19, 1886. She was a sister of Heroy Dyckman, Francis Dyckman, and business executive Richard P. Dyckman. Richard Dyckman served as the mayor of Plainfield, New Jersey and as a vice president of L.A. Dreyfus Company, now a subsidiary of the Wrigley Company. Dyckman was also a descent of Dutch farmer William Dyckman, the namesake of Dyckman Street in Manhattan; William Dyckman built the Dyckman House (now the Dyckman Farmhouse Museum), the oldest farmhouse in Manhattan. At the age of four, Dyckman moved with her family to Orange, New Jersey.
In 1905, Dyckman graduated from the Beard School (now Morristown-Beard School) in Orange after taking classes in the Latin-Scientific course of study. (Classmates and friends spelled her name Marie rather than Mary.) Astronomy was her favorite subject at school. Dyckman's father, Francis, wanted her to have diverse, enriching experiences as a child. He brought her to see the conditions of factory workers; this influenced her later interest in occupational health and safety. During high school, Dyckman and her family took a trip to Europe. During their visit to Italy, she began developing an interest in challenges faced by foreign workers. During her studies, Dyckman worked as a visiting caseworker in Orange, New Jersey and the New York City borough of Brooklyn. During her time at the later, she assisted the activities of the committees to address tuberculosis and manage general finances. Dyckman later served as assistant financial secretary for the New York Charity Organization Society, and she chaired the casework committee of the Family Welfare Association of America. In 1930, she helped organize the advocacy activities of a group that sought to sell the municipal light plant in Orange, New Jersey. The group's work led to the passage of a citizen's referendum that sold the plant. Six years later, Dyckman retired from her professional activities as a social worker, and she moved on to volunteer cases.
