Early Years and EducationSri Rajangam was born as the second son of Mada Theru Manaankutty Iyer. He had six siblings, including three elder sisters, an elder brother and two younger sisters. Rajangam studied at Ambasamudram and Maharaja's College, Trivandrum (today University College Thiruvananthapuram) and later obtained his bachelor's degree in engineering and mechanical engineering diplomas from College of Engineering, Guindy at Madras city, thereby becoming the first graduate of his family.[7] Professional careerAfter completing his education as a mechanical engineer, Sri Rajangam first worked for 4 years at Negapatam (Nagapattinam) at the shops (central workshop before it was moved to Trichy in 1928) there. In 1929, he was appointed an assistant mechanical engineer. Until 1936, he served as assistant to works manager, assistant mechanical engineers in two locomotive districts and as personal assistant to the CME at Golden Rock Railway Workshop. In 1936, he was elected as associate member of the Institution of Locomotive Engineers (ILE) and served as the honorary secretary of the South India branch for many years. Circa 1945-1946, he was offered to head the Chittaranjan Locomotive Works. However, he could not take up the position as he developed cancer. Since 30 March 1947, he was on sick leave (at first for a month, subsequently for another month, and so on) and remained so on medical certificate, until his death on 13 February 1948.[8] In their official obituary,[7] the ILE described him as "one of the most progressive Locomotive men in India" and acknowledged his many ideas and suggestions that were incorporated in the workshops of the SIR. FamilyIn 1922, he married Lakshmi Rajangam (1910–2009), a famous Carnatic classical music composer, vocalist and violinist and litterateur, who was the daughter of T.S. Sankara Aiyar, Financial Commissioner, Railway Board.[9] Lakshmi was only 12 years old at the time of their wedding, as it was common practice then. The couple had two daughters (Saroja Krishnamurthy and Seetha Subramanian) and two sons (R.R.Sankarasubramanian aka Ramani and R.R.Balakrishnan aka Bala).[2] On 13 February 1948, at the age of 45, Sri Rajangam died due to cancer.[7][8] This was 6 months after the marriage of his eldest daughter Saroja Krishnamurthy to M. S. Krishnamurthy, brother of the famous Indian scientist M. S. Swaminathan (Father of Green Revolution in India). After his early death, his wife Lakshmi brought up their remaining 3 young children while she worked at All India Radio, Trichy as a Carnatic musician as well as a writer of published essays and one-act plays. .[10][11] Sri Rajangam was a regular listener of BBC Radio news and admired classical English literature. It was reminisced by his family that he could memorise and recall long excerpts from novels by Walter Scott or Oliver Goldsmith with ease. See also
