Nobel prizes were created by the will of Alfred Nobel, a notable Swedish chemist, mainly to recognize contributions which could benefit humanity.
Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace. There was no Nobel prize in math. Possibly because Nobel didn't care much for mathematics and did not consider it a practical science from which humanity could benefit.
The Fields Medal is regarded as one of the highest honours a mathematician can receive, and has been described as the Nobel Prize of Mathematics.
The name of the award honours the Canadian mathematician John Charles Fields.
The Fields Medal is a prize awarded to two, three, or four mathematicians under 40 years of age at the International Congress of the International Mathematical Union (IMU), a meeting that takes place every four years.
Manjul Bhargava, a Princeton University graduate and an US citizen, was the first mathematician of Indian-origin who received the medal in 2014.
Akshay Venkatesh, an Australian of Indian descent, received the Fields Medal in 1918.
