The ideas of inter-conversion of mass and energy existed in science since inception of mankind. Many scientists contributed to the topic, and it is equally possible that doctrines of many may have not seen the light of the day. In this regard works of Newton, S T Preston, Olinto de Pretto, Poincare, Hasenhorl , Soddi etc form conceptual basis of the mass energy equation. But first of all genuine equation of light energy mass inter-conversion equation is derived by Einstein but only under special or handpicked conditions. Thus Einstein has provided mathematical equation for Newton’s statement  that ‘gross bodies and light are inter-convertible to each other’.
