firm that was divested to various firms over time.
History
The institute was formed with the goal of basic research including trying to understand, in Hughes's words, "the genesis of life itself." Despite its principles, in the early days it was generally viewed as a tax haven for Hughes's huge personal fortune. Hughes was HHMI's sole trustee and he transferred his stock of

challenged its "charitable" status which made it tax exempt. Partly in response to such claims, starting in the late 1950s it began funding 47 investigators doing research at eight different institutions; however, it remained a modest enterprise for several decades.
The institute was initially located in

, in 1953. Hughes's internist,
Verne Mason, who treated Hughes after his 1946 plane crash, was chairman of the institute's medical advisory committee. By 1975, Hughes was sole trustee of the Howard Hughes Medical Institute, which in turn owned all the stock of the Hughes Aircraft Company.
In 1969, United States Congressman
Wright Patman "complained that the Hughes foundation was a tax‐evasion device," noting that the institute spent only $5.7 million for its operations between 1954 and 1961, a period during which Hughes Aircraft accumulated $76.9 million in profits. By 1975, it had also avoided certain stipulations of the 1969 reform act for charitable institutions due to legal filings by Hughes to change its operational status, with his objections going directly to the White House.
The institute moved to

, in 1976.
In 1993, the institute moved to its headquarters in Chevy Chase, Maryland.

It was not until after Hughes's death in 1976 that the institute's profile increased from an annual budget of $4 million in 1975 to $15 million in 1978 and prior to Hughes Aircraft sale the number had peaked to $200 million per year. At the time of the sale Hughes Aircraft employed 75,000 people and vast amounts of money from the approximate annual revenue of $6 billion were put into Hughes Aircraft internal research and development rather than the medical institute. Most of the money for the medical institute came from the operations at Ground System Group responsible for providing

. Since Hughes died without a will as the sole trustee of the HHMI, the institute was involved in lengthy court proceedings to determine whether it would benefit from Hughes's fortune. In April 1984, a court appointed new trustees for the institute's holdings.
In January 1985 the trustees announced they would sell Hughes Aircraft by private sale or public stock offering. On June 5, 1985

In 2025, HHMI cancelled their Inclusive Excellence 3 (IE3) program, which was a 6-year (2022–2028) $8.8 million award they had committed to the IMPACT STEM Network, which sought to enhance undergraduate science education and research.
