India is full of geniuses and innovators who have made us proud. Needless to say, our country's contributions to the field of science are some of the greatest. But here's the thing. Most of these scientists are either not well-known or not talked about enough. The years of hard work that these people have put in is immensely applaudable and deserves our attention. If you haven't heard of them, here are 15 lesser-talked about Indian innovators that you must take out time to read about:

1. Yellapragada Subbarow

Even if you don't understand the technicalities, I'm sure you know what cancer is. This Indian biochemist discovered the function of adenosine triphosphate as an energy source in the cell, and developed methotrexate for the treatment of cancer! Guess who's helping us out, immensely?

2. Satyendra Nath Bose

He is 'one of those' who actually met Albert Einstein to formulate a theory related to the gas-like qualities of electromagnetic radiation! Indeed a brilliant mathematician and physicist.
