Dharmendra Kumar Tyagi, better known as Deep Tyagi or DK Tyagi (1928–1969), was an Assistant Commissioner for the Indian Family Planning program until 1969. An early pioneer of family planning in India and elsewhere, he was a champion of the program under the premierships of Jawaharlal Nehru, Lal Bahadur Shastri, and the initial period of Indira Gandhi. He invented the now-pervasive (in India and some other countries) "Red Triangle" symbol as a branding effort to familiarize and popularize the idea of family planning.
