Lee died Sunday, according to a Samsung statement. He had been hospitalized since a heart attack in 2014, and was treated for lung cancer in the late 1990s.
Lee once told employees to “change everything except your wife and children” in the days when he worked to transform Samsung from a copycat appliance dealer into a technology giant. In the process, he became South Korea’s richest person, with an estimated net worth of $20.7 billion, according to the Bloomberg Billionaires Index.
Samsung, the biggest of South Korea’s family-run chaebol, has been led by his only son, Jay Y. Lee, since the heart attack.
“Chairman Lee was a true visionary who transformed Samsung into the world-leading innovator and industrial powerhouse from a local business,” the company said. “His legacy will be everlasting.”
