C Ramakrishnan

Content Description

The accession consists of papers belonging to Chandrasekharan Ramakrishnan known to his students and colleagues as CR, a molecular biophysicist who worked on bond angles in proteins. 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).

Condition Description

The material is generally in a good condition. The lab notebook is a bit fragile, many of the pages are coming loose of their binding and some are tearing at the edges. Some of the correspondence printouts are on old and on thin paper, which appears fragile. Some of the papers in the correspondence files are also tearing at the edges.
