James Loewenberg, who designed and developed buildings that encompassed 45,000 residential units and more than 500,000 sq ft of commercial space along Chicago's North Lake Shore Drive, died Oct. 14 of pancreatic cancer at age 86, said Magellan Development Group, the company he co-founded and led with partner Joel Carlins.
Magellan is known for its development of Lakeshore East, a 28-acre, $4-billion neighborhood east of Michigan Ave. that is built on the former site of the Illinois Central Railroad's old Chicago yards. Loewenberg, an architect turned developer, was its co-CEO with Carlins until last year.
