On February 28, 1928, at the Indian Association for the Cultivation of Sciences, Kolkata (IACS), C V Raman and his associates showed that when monochromatic light is scattered by transparent media, the scattered light contains not only the original colour, but also other colours. This effect was named as Raman effect. In 1930, for the discovery of the Raman effect and work done on light scattering Raman received the Nobel Prize: the greatest award in the whole world. On the occasion of the 90th anniversary of the Raman effect, a brief  overview about the discovery and its reception by the scientific community is given here.

The first three decades of the 20th century are considered as the “Golden Period” of “Indian Physics”. The well-known facts are: In the beginning of the 1920s; M N Saha gave the Saha ionisation (also known as Saha-Eckert Equation), which explained the structure of stars [1]. On June 4, 1924, S N Bose wrote a letter to Albert Einstein, in which he stated that he (Bose) has derived Planck radiation law by applying his (Einstein’s) quantum nature of light. Einstein translated Bose’s manuscript, which was published in the German journal “Zeitschrift für Physik” [2]. Einstein further developed Bose’s idea. Consequently Bose-Einstein emerged [3]. In 1928 C V Raman, K S Krishnan and S Venkateswaran (Fig 1) discovered the Raman effect.
