Jaipur: India's youngest patent-holder Hridayeshwar Singh Bhati died here late on Tuesday night after suffering a cardiac arrest at the age of 19, according to family sources.
Bhati suffered from rare genetic disorder Duchenne muscular dystrophy and had 85 per cent disability.
"Hridayeshwar suffered a cardiac arrest at 1 am and passed away," the family sources said on Wednesday.
Bhati had seven inventions and three patents to his name and was awarded the 'Pradhan Mantri Rashtriya Bal Shakti Puraskar' in January last year. The award citation recognised him as the youngest patent-holder of India and the youngest differently-abled patent-holder of the world.
He also won the National Award for the Empowerment of Person with Disabilities in 2019 in the "Outstanding Creative Child (Male)-2019" category for excellence in the field of innovation.
Bhati was inspired by late British physicist Stephen Hawking, who also had a motor neurone disease. He initially invented a six-player circular chess in 2013 and got a patent for it. Later, he developed 12 and 60-player circular chess and got patents for them.
