Dr. A.P.J. Abdul Kalam is an Indian scientist and administrator who served as the eleventh President of India. He is a man of mission and vision. Millions of people, more particularly children are motivated by him. As a great humanitarian, he extended his knowledge of science and space technology to help disabled children, replacing their 3-kg metal supporters with light braces made of carbon weighing just 300 grams. His modesty is evident from the fact that he gives all the credit to his colleagues.
