[quote] A battle ensued between the temporary administrator of the Hughes estate, cousin and lawyer William Lummis, and those who ran the Medical Institute.

[quote] After years of struggle trying to sort the people with legitimate claims from the fakers who were in it to try to grab some of the cash, a lot of the money did end up going to the Howard Hughes Medical Institute. However, a huge chunk of it also went to various Hughes heirs. According to the Wall Street Journal, around 1000 people have benefited from the estate, including 200 of Hughes’ distant relatives. After liquefying many of his assets, they collectively were awarded about $1.5 billion.
[quote] the liquidation of the estate wasn’t completely finalized until 2010, 34 years after his death.
