Before inventing the Gong and Signal Chair, Miriam worked as a schoolteacher. Details about which schools she taught at, and what subjects she taught, remain unknown but relevant.

Miriam worked as a clerk in the federal government in Washington, D.C. The specific government agency in which she worked is unknown. This position likely provided her with a stable income and exposure to the inner workings of the government. This allowed her to support herself.

Details about her professional life following her work in the federal government are lacking. Whether she returned to teaching, pursued other entrepreneurial ventures, or continued in government service needs to be explored. Did her patent influence the direction of her working life?
