I came to know from media reports and Twitter posts that biologist Dr. Sohan Modak passed away on March 23rd. Although I never interacted with him directly I do have some distinct memories of his presence on the Pune University campus when I was completing my Masters in Geology in the late 1980's. On various occasions there were protests and strikes organized by faculty in opposition to some decision regarding University functioning. I don't remember Dr Modak ever making common cause with the rest of the faculty regarding going on a strike. He used to show up to the canteen with large posters which outlined his opinion of the situation. He then used to vociferously appeal to the faculty to get back to teaching.
On the academic side, many of my college batch mates had opted for a Master's in Zoology. I started hearing a different language from them. There was less emphasis on the rigid divisions between Zoology and Botany. Instead, universal mechanisms underlying all life were being discussed. Gene regulation, chromosome structure, development. All this was new and alien to me, but exciting to hear about none the less.
Dr. Modak had played a big role in the transformation of biology syllabus I was told. The various tributes now poring in bears this out.
R.I.P.
