Abel, a small child when Buffett took the helm at Berkshire Hathaway, runs the conglomerate’s noninsurance businesses.

Abel was named vice chairman of Berkshire Hathaway in 2018. Although he has been at the company for more than two decades, he is considered to be much more guarded and hands-on than Buffett.

He described his Edmonton neighborhood in Alberta, Canada, as working-class and family-oriented. He lives in Iowa with his family.
