The story
Dwarkadas Narendas Sampat (1884–1958) started his career in Indian cinema in 1904, when he brought a projector and began to organise film screenings in Rajkot, Bombay Presidency. He later entered film production and, through a partnership with S. N. Patankar, established Patankar Friends & Co, which, according to Rajadhyaksha and Willemen, 'took off in 1917' with Sampat's entry.
Film historian Amrit Gangar notes that Sampat established the Kohinoor Film Company after differences with Patankar.
The studio also trained such people as Nandlal Jaswantlal and Mohan Bhavnani, and produced artists such as Goharbai, Zebunissa and Rampiyari.
Along with Ranjit Movietone and the Imperial Film Company it was the largest movie studio when Indian talkies began in the 1930s.
