India's ex-president APJ Abdul Kalam dies

GAUHATI: Former Indian President APJ Abdul Kalam, who was known as the father of the country's military missile programme, died Monday after collapsing while delivering a lecture, a top state official said. He was 83.

The president from 2002 until 2007, he was a scientist and science administrator for four decades before that, mainly at the state-run Defense Research and Development Organization and the Indian Space Research Organization. He played a key organizational and technical role in India's nuclear program.

Kalam fell sick Monday while addressing the students of the Indian Institute of Management in the Meghalaya state capital, Shillong, said B. Warjri, chief secretary of the state. He was rushed to the hospital, but was declared dead after doctors could not revive him, Warjri said.

The federal government would declare national mourning for seven days for him, said federal Home Secretary L.C. Goyal.

"He was an inspiration to an entire generation," Home Minister Rajnath Singh tweeted.

After his presidential term ended, Kalam traveled to remote schools and colleges, speaking to students and inspiring them to follow their dreams.

Even after he left office, he received hundreds of emails each day from high-schoolers and young people seeking his advice. He would reply to most of the children who wrote to him.
