M. J. Thirumalachar

M. J. Thirumalachar is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand M. J. Thirumalachar rather than just read about it. In short: Mandayam Jeersannidhi Thirumalachar (22 September 1914 – 21 April 1999) was an Indian mycologist, microbiologist, plant pathologist and the co-founder of Jeersannidhi-Anderson Institute, California. He was the head of R&D at Hindustan Antibiotics Limited and a professor at Banaras Hindu University as well as the Central College of Bangalore.

Key takeaways

  • M. J. Thirumalachar belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect M. J. Thirumalachar to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of M. J. Thirumalachar from memory before moving on to harder problems.

Reference excerpt

Mandayam Jeersannidhi Thirumalachar (22 September 1914 – 21 April 1999) was an Indian mycologist, microbiologist, plant pathologist and the co-founder of Jeersannidhi-Anderson Institute, California. He was the head of R&D at Hindustan Antibiotics Limited and a professor at Banaras Hindu University as well as the Central College of Bangalore. He was known for the development of antifungal antibiotics such as Hamycin, Dermostatin, Aureofungin, MYc-4 and Tetraenenin and was an elected fellow of the Indian National Science Academy. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards for his contributions to Medical Sciences in 1967.

Biography

M. J. Thirumalachar was born in the erstwhile Mysore State of British India on 22 September 1914 to Vengadammal - M. J. Narasimhan couple as their second child. His father was a plant pathologist and mycologist after whom two genera of fungi (Narasimhella and Narasimhania) have been named. The young boy was named after his great-grandfather, Jeersannidhi Thirumalachar Swamy, erstwhile head of Sri Yadugiri Yathiraja Mutt, a vaishnavite religious center situated in Melukote. After early schooling in Malleswaram, a neighborhood of Bengaluru, he graduated from Central College, Bangalore before earning a Doctor of Science from the University of Mysore in 1944 and moved to the University of Wisconsin from where he secured a PhD in 1948 working under the supervision of James G. Dickson. On his return to India, he served at Banaras Hindu University as the head of the department of Mycology and Plant Pathology and at the Central College of Bangalore. Subsequently, he joined Central Potato Research Institute, Patna as the Chief Plant Pathologist but moved to Hindustan Antibiotics Limited (HAL) where he headed the R and D division. He served out his regular career at HAL, superannuating as the superintendent of research in 1975. Later, he returned to the US and served as a professor at the Department of Pediatrics of University of Minnesota Medical School where he worked on the incorporation of human insulin gene in yeast cells and also had a short stint as a visiting scientist at the Danish Institute of Seed Pathology, Copenhagen. In 1979, he founded Jeersannidhi Anderson Institute, along with his son, M. J. Narasimhan Jr., for advanced research in mycology and plant pathology and was the director of the institute till the end of his life. Thirumalachar's family produced four notable mycologists; M. J. Narasimhan (father), M. J. Narasimhan jr. (son) and M. C. Srinivasan (nephew), besides himself. He spent the last two decades of his life in Walnut Creek, California and it was here he died on 21 April 1999, at the age of 84.

Worked examples

Example 1 — a first encounter with M. J. Thirumalachar

Start with the simplest possible case. Write down what M. J. Thirumalachar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to M. J. Thirumalachar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about M. J. Thirumalachar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of M. J. Thirumalachar

In research
M. J. Thirumalachar appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses M. J. Thirumalachar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
M. J. Thirumalachar is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1914 births, 1999 deaths, 20th-century Indian biologists, so understanding it makes those chapters shorter.
In everyday life
Look for M. J. Thirumalachar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
