[Ed. – David Koch himself ran as the Libertarian Party’s vice presidential candidate in 1980.]
“It is with a heavy heart that I announce the passing of my brother David,” Charles Koch said in a statement Friday. “Anyone who worked with David surely experienced his giant personality and passion for life.”
Charles Koch did not say how his brother died, but David Koch blamed deteriorating health when he stepped down last year from Koch Industries, a Kansas-based energy and chemical corporation with an annual revenue of about $110 billion.
David Koch, regarded as the more gregarious of the two brothers, served as the executive vice president of Koch Industries. He held a master’s in chemical engineering from the Massachusetts Institute of Technology.
The brothers were tied as 11th richest in the world this year in a ranking by Forbes. At the time of his death, David Koch was worth $42.4 billion.
