During the 1980s and 1990s, Blankenstein became well known internationally for being one of the first openly homosexual
football referees. Blankenstein was active in various anti-discrimination charities and was a celebrity in the Netherlands. For breaking with the
taboo on the subject of homosexuality in football, the Dutch
LGBT advocacy organization
COC Nederland awarded him the Bob Angelo medal in 2003. Until June 2004, Blankenstein was chairman of COC Haaglanden, the branch of COC Nederland in the city of
The Hague. During the summer of 2004, he became one of the founders of
Homo LesBische Federatie Nederland. In 2005, he was awarded the Harry Stapels Award by the sports organization, NCS, for ten years of supporting the
emancipation of homosexual sportsmen and -women. On Friday, 25 August 2006, Blankenstein died in the Leyenburg Hospital in The Hague, Netherlands due to a rare
kidney-related disease. To continue his work for acceptance of and equal rights for homosexual people in sports, the
John Blankenstein Foundation was founded on 18 December 2008. On 13 January 2009, the city of The Hague established an annual award for gay-emancipation and named it the
John Blankenstein Award in his honor. ==References==
