Robert M. Sigler Jr. ’66

Bob died Dec. 13, 2024, ending a decade-long struggle with Alzheimer’s and Parkinson’s diseases.

Bob graduated from the Seaholm School in Birmingham, Mich. At Princeton, he majored in electrical engineering, belonged to Dial Lodge, was manager of the student laundry, and held a position in the St. Andrew’s Presbyterian Church choir.

After graduation he enrolled in the University of Michigan Law School. Following admission to the Michigan bar, he joined General Motors as a patent attorney.

Drafted by the Army in 1970, he was stationed at Dugway Proving Grounds in Utah. Although titled electrical engineering assistant, he devoted most of his time to assisting JAG attorneys.

When his Army tour ended, Bob returned to the GM patent department. He worked there until GM spun off Delphi, where he completed his career as patent attorney.

Music was central to Bob’s life. He began singing in a boy choir and sang in choirs for the rest of his life. Already proficient on the guitar, in the 1970s he mastered the lute and became active in the Lute Society of America.

The class extends is heartfelt condolences to Julie, Bob’s wife of 53 years; and to sons Daniel, Mark, and Bill.
