Man who inspired ice bucket challenge dies aged 34
Pete Frates' battle with amyotrophic lateral sclerosis (ALS) inspired the internet phenomenon that raised millions for research.
Pete Frates, whose battle with motor neurone disease inspired the ice bucket challenge, has died aged 34.
Everyone from Donald Trump to cartoon character Homer Simpson, and probably many of your friends and family, took part in the internet phenomenon when it exploded into life in 2014.
The challenge, which saw participants drenched by a cold bucket of water filled with ice before nominating others to go through with it too, took social media by storm largely thanks to Mr Frates, a former college baseball player.
He was diagnosed with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease and motor neurone disease, in 2012 at the age of 27 after noticing that a wrist injury sustained while playing baseball was not healing properly.
Two years later he helped draw attention to the ice bucket challenge and it has since raised about $220m (£167m) worldwide, with famous faces including Bill Gates, George W Bush and Tom Cruise among those who took part.
