Academic and Research Achievements: Indar Jit Dewan was a teacher of Anatomy since 1944. His outstanding work includes structure and development of sphincters of the gut and structure, and development of the Treitz muscle. He found out the nerve supply of this muscle, which had not been described earlier. He described the development of muscularies submucosae ani and showed that anal valves and ileal bands were present only in man and developed with erect posture. Several of his research papers were devoted to age estimation and sexing of skeletal remains, the latest being on ‘time of fusion of the basi-spheniod with basilar part of the officipal bone’. His studies on ageing and sexing the clavicle are of great importance in forensic work. One of his findings showed that by taking certain X-rays one can find out whether a girl is above or below sixteen years. This finding is being extensively used in cases falling under Section 375 of Indian Panel Code. His studies on brain weight showed that brains of women weighed 100g less than that of men which, in turn, weighed less than that of the Caucasians. He, however, added that weight and intelligence, within limits, do not go together and that even women with smaller brain weight could be more intelligent than men.
