Greg Reiter, Wells Fargo & Co.’s head of residential mortgage research who spent more than 25 years specializing in bonds backed by home loans and other securities, died Oct. 16 at his home in Middleburg, Va. He was 52.

A spokeswoman for the San Francisco-based bank announced the death. The cause was injuries from an accident.

Mr. Reiter, a managing director in Wells Fargo’s New York office, was named to his position in 2012. He joined the bank from Freddie Mac, the McLean, Va.-based mortgage-finance company controlled by the U.S. government, where he was responsible for developing securitization strategies.

Mr. Reiter previously was a managing director and head of agency mortgage-backed securities strategy at Royal Bank of Scotland, based in Great Britain, and he held similar positions at UBS Group, based in Switzerland, and Amherst Securities Group, based in Houston.

This month Mr. Reiter told colleagues that he was leaving Wells Fargo and joining a real estate credit management firm backed by Amherst Holdings.

After the 2008 financial crisis, Mr. Reiter was closely engaged with policymakers, investors and banks to discuss the role of private capital in U.S. housing finance and the recovery of the mortgage market. He wrote regularly about recent initiatives of government-backed Fannie Mae and Freddie Mac to transfer credit risk to private investors.

Gregory James Reiter was born in San Diego on June 6, 1963. He was an economics graduate of the University of California at Berkeley, where he also received a master’s degree in business administration.

Those who worked with Mr. Reiter remember that he did not wear leather shoes in the office, because of his support of animal rights. Over the years, he adopted two abandoned horses, rescued four dogs and more than twice as many cats.

“We rescued many animals together,” his wife, Alysoun Mahoney, said in a statement. “We went the path of being vegetarian and ultimately vegan together, and for many years have been active supporters of many animal advocacy organizations.”

In addition to his wife of 23 years, survivors include his father and a sister.
