In 1954, Bucksbaum and his brother Martin borrowed $1.2 million and built the first shopping center in Cedar Rapids, Iowa, anchored by a fourth family grocery store. They expanded into enclosed malls which mirrored the continued movement to the suburbs seen in the 1960s. By 1964, their company - then named General Management - owned five malls anchored by the Younkers department store. In 1972, the company became publicly traded on the New York Stock Exchange under the name General Growth Properties (NYSE: GGP) and became the second-largest owner, developer, and manager of regional shopping malls in the country. Bucksbaum served as its Chairman and Chief Executive Officer and under his tenure, he formed two Real estate investment trusts and expanded the company's portfolio of malls and shopping centers via more than $36 billion in acquisitions. In 1984, General Growth sold 19 malls for $800 million to Equitable Real Estate, which was deemed the “nation’s largest single asset real estate transaction” to date. In 1995, his brother Martin died and he re-located the company to Chicago. In 2004, General Growth purchased The Rouse Company for $14.2 billion. By 2007, General Growth was the second-largest REIT owning 194 malls with over 200 million square feet in 44 states. In 2008, General Growth filed for Chapter 11 bankruptcy protection after the collapse of the stock market.
