Dr Kalam received India’s highest civilian honour, the Bharat Ratna, in 1997 for his contribution to the scientific research and modernisation of defence technology in India. In 2013, he was the recipient of the Von Braun Award from the National Space Society “to recognise excellence in the management and leadership of a space-related project”.

From his early struggles to get the proper education to his contributions to India’s civilian space program and military missile development efforts, Dr Kalam’s life story has been nothing short of a stirring journey. Dr Kalam’s work in science with the Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO) ranging to a span of four decades played a key role in putting India on the international map. APJ Abdul Kalam also excelled as an author, inspirational speaker, scientist, researcher and much more. Mr Kalam played a pivotal organisational, technical and political role in India’s Pokhran-II nuclear tests in 1998, the first since the original nuclear test by India in 1974.

Dr APJ Abdul Kalam passed away on July 27, 2017, from a cardiac arrest while delivering a lecture at the Indian Institute of Management Shillong. The sudden death of Dr Kalam left the world at a standstill and thousands of people attended his funeral that was held in his hometown, Rameshwaram.

Fondly remembered as the ‘People’s President’, he was honoured with prestigious awards such as Padma Vibhushan, India’s second-highest civilian award, and Bharat Ratna, the country’s highest civilian award. Kalam died on 27 July 2015 at IIM Shillong while delivering a lecture to students. His last words reportedly were to his long-time aide Srijan Pal Singh “Funny guy! Are you doing well?”
