Biography

Ramchundra's father, Rai Sunder Lal Mathur, was employed in the Indian revenue department and, at the time of Ramchundra's birth, he had been posted to Panipat which is a city in north west of India about 70 km from Delhi. In fact the family came from Delhi and they were of the Kayastha caste, that is a Hindu caste of scribes who worked in the Indian bureaucracy. Ramchundra's early education was at home, a standard for India at that time, but he also attended school in Panipat from the age of six.

Ramchundra (Ramachandra Lal) (Devanagari,रामचन्द्र लाल) (c. 1821–1880) was a British Indian mathematician. His book, Treatise on Problems of Maxima and Minima, was promoted by mathematician Augustus De Morgan.

Writing in his preface to the treatise, De Morgan states that Ramchundra was born in about 1821 in Panipat to Sunder Lal, a Kayasth of Delhi. He came to De Morgan’s attention when, in 1850, a friend sent him Ramchundra’s work on maxima and minima. The 29-year-old self-taught mathematician had published the book at his own expense in Calcutta in that year. De Morgan was so impressed that he arranged for the book to be republished in London under his own supervision, and in general undertook to bring Ramchundra's work to the notice of the broader European scientific community. Quoting De Morgan, from the preface of the treatise:
