Berkshire Hathaway’s The Lubrizol Corporation has appointed Mary Rhinehart as president and CEO on an interim basis, effective immediately.

Rhinehart currently serves as the chair of Lubrizol’s board. She succeeds Chris Brown, who joined Lubrizol in 2021 to help the company with important work around safety and operational excellence.

Rhinehart also serves as board chair of Berkshire Hathaway’s Johns Manville, a global building and specialty products manufacturer. She became Johns Manville’s president and CEO in 2012 and assumed the additional role of chair in 2014. Prior to these roles, she was the company’s chief financial officer for eight years. During her more than 40 years with Johns Manville, she held leadership roles in treasury, supply chain, mergers and acquisitions, and human resources. She also managed several of the company’s business units.

Rhinehart will lead the search and selection process for a new CEO and will continue to serve as Lubrizol’s board chair.

“It is an honor to serve in this role for a company with such a rich heritage as a leader in the chemical industry,” Rhinehart said. “I look forward to working alongside Lubrizol’s dedicated employees to continue to deliver value for our customers and support our communities.”
