Born on the 28th of September 1935, in Piplan (in erstwhile Panjab, now in Pakistan), young Gulati lost his parents during the 1947 war following the partition between India and Pakistan. He arrived as a refugee with his brothers and sisters in New Delhi where he had his school and university education (see also Parma, 2003). He obtained his B.Sc. honours in Zoology (1956), and M.Sc. in Fish and Fishery Biology (1958) from the Department of Zoology, University of Delhi. For his PhD degree (1964, University of Delhi), he had investigated several shallow and deep lakes including Lake Nainital and Lake Bhimtal in the Kumaon Himalaya. He had studied thermal stratification, plankton ecology, algal blooms and lake eutrophication. These studies, however, remain unpublished. He taught zoology to graduate students from 1959 to 1968 at Delhi University, before moving to the Netherlands.
Career in the Netherlands The waterscape of the Netherlands is dominated by a large number of freshwater lakes, besides the rivers S. S. S. Sarma S.

and canals. These lakes, created since the early 17th century by dredging out peat, have undergone eutrophication since early 1950s due to growing input of nutrients from agriculture and polluted waters from the rivers and canals (Gulati & van Donk, 2002). As elsewhere in Europe and North America, the problem of eutrophication of lakes attracted much attention in the Netherlands as well, leading to the establishment of the Hydrobiological Institute in 1957. After the sudden untimely demise of its first director, Dr. E. Nicolai, Dr. H.L. Golterman, the only other scientist in the Institute at that time, became its Director. Dr. Golterman laid the foundations of research in physical–chemical limnology, focusing especially on the phosphorus dynamics, both in the water column and in the mud-water interphase. Recognizing the need to investigate the role of biological components of lake
