After a somewhat tentative debut in Jwar Bhata and Pratima, the actor came of age in Milan, which was followed by the super-duper hit Jugnu opposite none other than Noor Jehan. Dilip Kumar had now hit the purple patch of his career and three mega hits followed in quick succession —Shaheed, Shabnam and Nadiya Ke Paar. The leading lady of all these hits was the comely Kamini Kaushal—reportedly Dilip Kumar's first flame and also his first serious heartbreak.

Kamini Kaushal's real name was Uma Kashyap. She was the daughter of Rai Bahadur S.R. Kashyap, a renowned Botanist, president of Indian Science Congress and dean of the pre-partition Punjab University. She was one of his five children which included three brothers and two sisters. She was very well-educated and had studied at Lady MacLagan School and Emily Kinnaird College of Lahore. She was also a champion swimmer. When her elder sister, who was married to B.S. Sood, a high ranking official of Bombay Port Trust, died in a car crash leaving behind two small kids, Uma married him and moved to Mumbai. It was here that legendary director Chetan Anand discovered her talent and cast her in his award-winning Neecha Nagar as Kamini Kaushal. As an actress, she quickly ascended to stardom with films like Jail Yatra, Aag (opposite Raj Kapoor), Do Bhai, etc. Soon, Filmistan's S. Mukerji signed her opposite Dilip Kumar in his Shaheed (1948) which was a box-office success.
