From 1876 until 1879 Keith taught in the public school system of Massachusetts. Four years later, in 1883, she began to work as a science instructor at the Michigan Seminary, in Kalamazoo[4] until 1885. Beginning in 1885, Keith taught mathematics at Mount Holyoke, and then became the school's first full-time teacher in the physics department there. From 1889 until 1903, Keith was the head of the department.[1] In 1904, Keith taught at Norton.[4] She taught at Lake Erie College in Painesville, Ohio,[4] from 1905 until 1906.[5]
Keith was a pioneer in the education of women in the science of physics. It is believed that she is the first to introduce individual laboratory work to students.[5] She also launched the physics colloquium at Mt. Holyoke in order to increase awareness among students of the growing field of physics.[5]
Research
Keith investigated the physics of heat transmission in gases at low temperatures.[5]
Keith was a charter member of the American Physical Society, helping to establish the group in 1899.[1] Keith and Isabelle Stone of Vasser were the only two women in attendance at the founding of the group.[5]
Family
Marcia Anna had four sisters, Lucy Keith, Mary Helen Keith, Sarah Emma Keith, and Cora Frances Keith, and a niece, Mary Keith Warren.[4]
