Har Gobind Khorana

Har Gobind Khorana (9 January 1922 – 9 November 2011) was an Indian American biochemist. While on the faculty of the University of Wisconsin, he shared the 1968 Nobel Prize for Physiology or Medicine with Marshall W. Nirenberg and Robert W. Holley for research that showed the order of nucleotides in nucleic acids, which carry the genetic code of the cell and control the cell’s synthesis of proteins. Khorana and Nirenberg were also awarded the Louisa Gross Horwitz Prize from Columbia University in the same year.

Srinivasa Ramanujan

Srinivasa Ramanujan was an Indian mathematician who lived during the British Rule in India. Though he had almost no formal training in pure mathematics, he made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions, including solutions to mathematical problems considered to be unsolvable.

During his short life, Ramanujan independently compiled nearly 3,900 results (mostly identities and equations). Many were completely novel; his original and highly unconventional results, such as the Ramanujan prime, the Ramanujan theta function, partition formulae and mock theta functions, have opened entire new areas of work and inspired a vast amount of further research.

Known for

  • Landau–Ramanujan constant

  • Mock theta functions

  • Ramanujan conjecture

  • Ramanujan prime

  • Ramanujan–Soldner constant

  • Ramanujan theta function

  • Ramanujan's sum

  • Rogers–Ramanujan identities

  • Ramanujan's master theorem

  • Ramanujan–Sato series


  • Fellow of the Royal Society


  • Mathematics


  • Trinity College, Cambridge

Jagadish Chandra Bose

Jagadish Chandra Bose

Sir Jagadish Chandra Bose was a polymath, physicist, biologist, biophysicist, botanist and archaeologist, and an early writer of science fiction from British India. He pioneered the investigation of radio and microwave optics, made significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent. IEEE named him one of the fathers of radio science. Bose is considered the father of Bengali science fiction, and also invented the crescograph, a device for measuring the growth of plants. A crater on the moon has been named in his honour.

Known for          

  • Millimetre waves

  • Radio

  • Crescograph

  • Contributions to plant biology


  • Companion of the Order of the Indian Empire (CIE) 1903

  • Companion of the Order of the Star of India (CSI) 1911
