Theodore William Chaundy (19 January 1889 – 14 April 1966) was an English mathematician who introduced Burchnall–Chaundy theory.
Chaundy was born to widowed businessman John Chaundy and his second wife Sarah Pates in their shop-cum-home at 49 Broad Street in Oxford.
John had eight children, one of whom died as a toddler, with his late first wife and died barely a year after Chaundy was born.
The Chaundy home along Broad Street has since been demolished.
[1] Chaundy attended Oxford High School for Boys and read mathematics at Balliol College, Oxford on a scholarship.
