who is called the missile man of india
A. P. J. Abdul Kalam Avul Pakir Jainulabdeen Abdul Kalam better known as A. P. J. Abdul Kalam (/ˈæbdʊl kəˈlɑːm/ ( listen); 15 October 1931 – 27 July 2015), was the 11th President of India from 2002 to 2007. A career scientist turned statesman, Kalam was born and raised in Rameswaram, Tamil Nadu, and studied physics and aerospace engineering. He spent the next four decades as a scientist and science administrator, mainly at the Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO) and was intimately involved in India's civilian space programme and military missile development efforts.[1] He thus came to be known as the Missile Man of India for his work on the development of ballistic missile and launch vehicle technology.[2][3][4] He also 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.[5]
Vallabhbhai Patel As the first Home Minister and Deputy Prime Minister of India, Patel organised relief efforts for refugees fleeing from Punjab and Delhi and worked to restore peace across the nation. He led the task of forging a united India, successfully integrating into the newly independent nation those British colonial provinces that had been "allocated" to India. Besides those provinces that had been under direct British rule, approximately 565 self-governing princely states had been released from British suzerainty by the Indian Independence Act of 1947. Employing frank diplomacy with the expressed option to deploy military force, Patel persuaded almost every princely state to accede to India. His commitment to national integration in the newly independent country was total and uncompromising, earning him the sobriquet "Iron Man of India".[3] He is also affectionately remembered as the "Patron saint of India's civil servants" for having established the modern all-India services system. He is also called the Unifier of India.[4]
