In 1894 when Marcellus was a student (1893–1896) at Harvard Law School, he built his own telephone line to his parents' home and then established the Citizens Telephone Co. In 1910, Marcellus opened Joslyn Manufacturing & Supply Co., to manufacture telephone pole line hardware.
In the early 1950s, Joslyn worked with several airframe manufacturers and the Lightning and Transient Research Institute of Minneapolis to address post World War II concerns of lightning and electromagnetic pulse (EMP) impacts on aircraft HF radios. Over the next several years, he recruited electronics engineers to design and develop product lines. After becoming a supplier of aircraft lightning arresters, the company introduced products for electrical surge and transient protection for power, communications, transportation and industrial process control.
Joslyn's once said of his business philosophy, "Make no trade that is not good for both parties." The Joslyn plan called for labor and management working together and as Joslyn said, "No man amounts to anything by himself and one can only rise by the friendships and loyalties of those around him which can only be secured by thoughtfulness and courtesy and fairness".
Joslyn was president of the company until 1946 when he relinquished that office and became chairman of the board of directors.
Joslyn retired to Santa Monica, California, where he became involved in philanthropic interests.
