Though not a founding member, he also served as the president of the Indian Society of Soil Sciences. Dhar was also a member of the Society of Biological Chemists, India. In 1961, he became the General President of the Indian Science Congress Association.
Notes edit
- ^ Both institutions merged in 1980 as part of the formation of the Royal Society of Chemistry (RSC); the post-nominal became "FRSC" from that time.
- ^ Prior to 1970, the Indian National Science Academy was named the "National Institute of Sciences of India", and its fellows bore the post-nominal "FNI". The post-nominal became "FNA" in 1970 when the association adopted its present name.
