Sukumar Chandra Sirkar an unsung hero of ‘Calcutta School of Physics’ began his research career under C. V. Raman in the middle of 1920s. Sirkar witnessed the discovery of the Raman effect in 1928 and was the first person to study the intensity of Raman lines in Raman spectra. For more than half a century he was associated with the University of Calcutta and the Indian Association for the Cultivation of Science (IACS). Later, some of his students occupied higher positions in various institutions. Sirkar differed with his teacher C. V. Raman while interpreting the diffuse Laue spots observed in crystals. He was a Fellow of the Indian National Science Academy and associated with many other scientific institutions, such as Indian Science News Association and the journal Science and Culture. The paper attempts to highlight Sirkar’s role in development of Department of Optics at the IACS.

Sukumar Chandra Sirkar和IACS的光学系

Sukumar Chandra Sirkar是“ Calcutta物理学校”的无名英雄，他的研究生涯始于1920年代中期的CV Raman。Sirkar于1928年见证了拉曼效应的发现，并且是第一个在拉曼光谱中研究拉曼谱线强度的人。在半个多世纪的时间里，他与加尔各答大学和印度科学培养协会（IACS）有联系。后来，他的一些学生在各个机构中担任更高的职位。锡尔卡（Sirkar）与他的老师简历拉曼（CV Raman）不同，他解释了晶体中观察到的弥漫性劳厄点。他曾是印度国家科学院院士，并与许多其他科学机构有联系，例如印度科学新闻协会和《科学与文化》杂志。
