Joseph Scott Chamberlin, formerly of Darien, died Sept. 29 at his home in New Rochelle, N.Y.

Mr. Chamberlin was born in San Francisco in 1949, the son of the late Joseph W. Chamberlin and Jean Richardson Chamberlin, and moved with his family at an early age to Darien, where he attended public schools. He graduated from the Pomfret School in Pomfret, Conn., and attended American University in Washington, D.C.

Mr. Chamberlin spent many of his post-college years working as a farrier/blacksmith in the Pacific Northwest and, after that, in the film industry in Los Angeles.

Since moving to New Rochelle many years ago, Mr. Chamberlin held a variety of sales and service positions and was employed at the time of his death as a salesperson of organic farm products. He was a long-time volunteer for the WESPAC Foundation in New York, which promotes peace and justice issues, and was also actively involved as an advocate for many national environmental, green-building and social justice causes.

Mr. Chamberlin was also a passionate and deeply principled supporter of numerous local and regional initiatives to preserve endangered wildlife species, a collector of historical musical instruments and a student of 19th century photography and early film-making.

Survivors include his sisters, Jill Chamberlin McCormack of Tallahassee, Fla., Leslie Chamberlin Hunt of Sedona, Ariz., and Wendy A. Chamberlin of Bridgehampton, N.Y.; and nephews Kenneth Sullivan of Chicago, Sean Sullivan of Windham, N.H., and Garrett McCormack of Tallahassee, Fla.

A private memorial service will be scheduled at a later date.

Donations may be made in Mr. Chamberlin's name to WESPAC, 52 North Broadway, White Plains, NY 10603.
