Thomas Pragasam, (1941 to 2017) was one of the great founders and inspirations for the Pondicherry Science Forum. He was born on July 4th, 1941 and passed away in 3rd October 2017, at the age of 76 years. His formal occupation was as the Head Sarasdar in the Judicial Department, but he was one of the great science amateurs and innovators. He was well known for his work as a radio ham-enthusiast, and for time was president of the Ham association. He was a nature lover with special skills in cultivation of cacti and bonsai. He had a science laboratory where he did many experiments and taught experimental skills and electronic design and repairs to interested students. With the government he worked for introduction of mangroves in the estuaries near Puducherry and the design and establishment of the Rockery at the far end of the Promenade beach. He was one of the first persons to join PSF in 1985 and he remained active in the organisation till the very end. He married in 1965 and this was a long standing loving lifetime partnership. We are also proud to note that his daughter Alice and son-in-law Maran and son Theist have carried the tradition and continue to help PSF organise childrens science festivals and many other activities and his son.
