From a Washington Post obit by Adam Bernstein and Matt Schudel headlined “Ted Lerner, real estate magnate and Nationals owner, dies at 97”:

Theodore N. “Ted” Lerner, a self-made billionaire developer who became principal owner of the Washington Nationals and oversaw the team’s rise to prominence, capped by its victory in the 2019 World Series, died at his home in Chevy Chase, Md.

The pinnacle of Mr. Lerner’s stewardship of the Nationals came in 2019, more than a decade after he bought the franchise for $450 million. After a stumbling start to the season, the Nationals found a remarkable team chemistry that year, winning the National League pennant on Oct. 15 — Mr. Lerner’s 94th birthday.
