Alvin S. Lane, a former partner in a major New York City real estate law firm and a leader of efforts to protect art collectors from fraud, died Thursday in Manhattan. He was 89 and had homes in the Riverdale section of the Bronx and on Marthaâ??s Vineyard.
The art collection of Mr. Lane and his wife, the former Terese Lyons, which includes works by Picasso, Giacometti, Calder and Nevelson, is to be donated to the University of Wisconsin, Madison, where Mr. Lane graduated in 1940.
