Lynn G. Bellenger spent 200 days traveling the globe in her 2010-11 term leading the 55,000-member American Society of
Heating, Refrigerating and Air Conditioning Engineers. But Nancy Jendryaszek, with whom Bellenger co-founded Pathfinder Engineers & Architects LLP, Rochester, N.Y., says colleagues "found it amusing because Lynn was directionally challenged." A leader in energy modeling software development as well as being ASHRAE's first woman president, Bellenger died on Oct. 19 at age 62. The firm did not disclose the cause of death.
