Summary

Billy Evans is an American entrepreneur, hotel heir, and the husband of former Theranos CEO Elizabeth Holmes. Born into the Evans Hotels family—which operates notable hospitality properties in the San Diego, California area—Evans graduated from the Massachusetts Institute of Technology (MIT) and previously worked as a manager of special projects at Luminar Technologies, an autonomous vehicle LiDAR hardware company. Evans met Elizabeth Holmes in San Francisco in 2017 prior to her indictment by the U.S. Department of Justice, and the couple subsequently had two children together. Amid Holmes's conviction for financial fraud and her 135-month sentence at Bryan Federal Prison Camp in Texas, Evans has actively defended her against prevailing media narratives, appearing on the All-In Podcast with David Friedberg and participating in an A24 documentary directed by Nathan Fielder titled 'You Can See Everything'. Moving beyond the shadow of Theranos, Evans founded Hemanthes, a deep-tech startup that employs Raman spectroscopy and photonics to generate biological datasets for training artificial intelligence models.

  • Billy Evans – Society for American Baseball Research

    Billy Evans had one of the most varied nonplaying careers in baseball history. The third umpire to be inducted into the Hall of Fame, Evans umpired from 1906 to 1927 during most of the Deadball Era in the American League, and augmented his umpire’s salary by writing a nationally syndicated sports column, “Billy Evans Says,” as the sports editor of the Newspaper Enterprise Association. Prior to that, he had written columns that appeared in more than 100 newspapers across the country covering varied topics as player personalities, umpiring techniques, and the World Series. In doing this, he promoted and understanding of the game and its stars in the early 20th century. A popular offering was a frequent column on strategy and rules, with the pointed question, “What Would You Do?”1 [...] Born in Chicago on February 10, 1884, William George Evans grew up in Youngstown, Ohio, where his father, a Welsh immigrant, worked as a superintendent in a Carnegie Steel mill. As a youngster he participated in YMCA sports programs and a local baseball team, the Youngstown Spiders, named after the Cleveland Spiders. Billy enrolled at Cornell University in 1901. Having excelled in baseball, football, and track in high school, Evans played freshman football and baseball at Cornell University. His baseball coach, former Baltimore Orioles player and future Detroit Tigers manager Hughie Jennings, called Evans a fine outfielder, but Billy’s playing days ended with a football-related knee injury. [...] Evans quickly built a reputation as a “fair and square umpire” capable of handling any situation that arose on the diamond. He often said the trick of umpiring relied upon three talents: the ability to study human nature and apply the findings, the ability to be at the right angle to make a call and the ability to bear no malice. Billy demonstrated this third skill in St. Louis in September 1907, when his skull was fractured by a bottle thrown by a 17-year-old fan after a controversial call. Ban Johnson came to St. Louis to announce he had hired an attorney and would prosecute the young offender. To his dismay, however, Evans refused to press charges, saying the youth’s parents were nice people and the kid had apologized for throwing the bottle.9
