Rubin "Rubie" Schron is a New York City real estate investor, landlord, and the founder of Cammeby's International Group. He owns or controls property worth over $900 million, according to data company Real Capital Analytics. Founded in 1967, Cammeby's portfolio includes office buildings; market-rate and government-subsidized apartment complexes; nursing homes, the 16-building complex in Sunset Park now known as Industry City; a stake in the bottom half of the Woolworth Building; and industrial properties across Long Island. In 2013, Schron made an unsolicited and unsuccessful offer to buy the Empire State Building for $2 billion, but he has not had problems closing many other deals throughout his long career. In 2003, an investment group led by Schron paid $705.6 million for a portfolio of about 6,000 outer-borough apartments from Donald Trump. Other buildings he owns include the Monterey, a 521-unit rental multifamily building on Manhattan's Upper East Side; over the decades, Schron has also amassed a portfolio of Mitchell-Lama apartment buildings whose values have been skyrocketing to record values, after reverting to market rates when government subsidies expired. In 2007, he sold nearly 4,000 units of former Mitchell-Lama properties in five complexes in Harlem and on Roosevelt Island for $940 million. Schron, who practices Orthodox Judaism, has eight children and 50 grandchildren. He and his family have lived in the same single-family home in Brooklyn for many decades.
