List of Famous people with last name Holmes

Elizabeth Anne Holmes is a former American businesswoman who founded and was the CEO of Theranos, a now-defunct health technology company. Theranos soared in valuation after the company claimed to have revolutionized blood testing by developing testing methods that could use surprisingly small volumes of blood, such as from a fingerprick. By 2015, Forbes had named Holmes the youngest and wealthiest self-made female billionaire in America, on the basis of a $9-billion valuation of her company. The next year, following revelations of potential fraud about Theranos' claims, Forbes had revised its published estimate of Holmes' net worth to zero, and Fortune had named her one of the "World's Most Disappointing Leaders".

Herman Webster Mudgett, better known as Dr. Henry Howard Holmes or H. H. Holmes, was an American serial killer.

Victims were killed in a mixed-use building which he owned in Chicago, located about 3 miles (5 km) west of the 1893 World's Fair: Columbian Exposition, supposedly called the World's Fair Hotel, though evidence suggests the hotel portion was never truly open for business.
