CR's work was instrumental in the development of the well-known Ramachandran plots, named after his thesis supervisor G. N. Ramachandran (GNR). The accession contains hand-written and printed materials. The hand-written material includes a lab notebook (ca. 1966-1969) belonging to CR containing literature review, calculations, a computer program, and recorded data about bond angles. In addition, there is a folder containing handmade material (individual sheets of paper intended to be assembled together) for a poster presentation. There are also three files containing printed material, specifically correspondences between CR and journal editors regarding manuscripts intended for publication in scientific journals. One of these files pertains to manuscripts which were ultimately rejected. The other two files contain correspondences for accepted manuscripts, and are tabbed by publication number. In addition, the accession contains a printout of a chapter from the book "Biochemistry of Collagen" published by Plenum Press in 1976. The chapter was authored by GNR and CR. Lastly, the accession contains a bunch of miscellaneous printed matter - a datasheet of bond angles in the amino acid glycine (with handwritten annotations), a list of publications by CR (ca. 1991), and photocopies of journal papers (not authored by CR). Chandrasekharan Ramakrishnan (known as CR) was a molecular biologist from India. He was born in 1939. He was part of the Madras group in the 1960s where he worked on protein structures. He generated the first version of the iconic Ramachandran map as a PhD student, He was a faculty at the University of Madras(1964–1972) and then at the Molecular Biophysics Unit at Indian Institute of Science (1972–2001).He made contributions to peptide and protein conformational analysis and conducted studies of hydrogen bond geometry, cyclic peptide conformations and protein structural data analysis. His work furthered the understanding of peptide and protein structures.
