Schupbach was born Rosa Lechner on June 29, 1928, in Zürich, Switzerland to Florian (1886–1955) and Marie (née Ozeler).[4] Her maternal family originally hailed from the Ottoman Empire (today Turkey) with the original spelling of the last name being Özeler. Her fathers family had roots in the Russian Empire and became Swiss citizens in 1899 in Oerlikon which was integrated into Zürich in 1934.[5] She completed her Matura and completed two Master of Arts programs at Columbia University.

After her emigration, Schupbach initially held clerical positions in various companies, such as an office machinery store.[6] From 1962 to 1967 she held a position as economist at the Caltex Petroleum Corporation and subsequently became a legal assistant at Anderson, Russell Kill & Olick from 1971 to 1977. Schupbach then engaged as research assistant to professor Fritz Machlup in the Department of Economics at New York University. Her last position was at the National Bureau of Economic Research which she held until her retirement in 1990.

After marrying her Iranian husband in 1959 (which she shortly after divorced) she moved to London, England. Due to her marriage with an Persian she also automatically held Iranian citizenship. Under the old Swiss nationality law she initially lost her Swiss citizenship and was only later able to regain it through a administrative payment of 10 Swiss Francs. Since 1966, Schupbach held Swiss American dual citizenship.[7] Then she emigrated to the United States and settled down in New York City with only $2,000 in her name. In 1962, she married Edmund W. Schupbach, an American whom she met while working at Caltex Petroleum Corporation.

Schupbach died on January 11, 2022, aged 93 in her Upper East Side apartment.[8]
