His doctor told CNN that Saroj Khan, a famous Indian choreographer behind some of Bollywood’s biggest productions, died at the age of 71.

During his forty-year career, Khan performed hundreds of musical note choreographies and some of India’s biggest stars danced in his direction.

One of his doctors, Narendra Sharma, told CNN that he died of a cardiac arrest at the Guru Nanak Hospital in Mumbai on Friday. Khan was diabetic and was on dialysis, Sharma said. He said that he was struggling with an infection that eventually led to cardiac arrest.

Khan had been tested twice for Covid-19, but both tests were negative, Sharma added.

The hit songs from the movie “Devdas” such as “Dola Re Dola” and the 2007 comedy “Jab We Met (When We Met)” were prepared according to Khan’s choreography.

He was also recognized as a mentor to Bollywood’s most famous faces. Khan has worked with late artist Sridevi on many artists, including “Mr. India”, “Chandni” and “Lamhe”, and choreographed dozens of Bollywood senior Madhuri Dixit.

Dixit was among the stars to pay tribute to Khan on Friday: “I was devastated by the loss of my friend and my guru Saroj Khan. I always appreciate it helping me reach my full potential in the dance. The world has lost an incredibly talented person. I will miss you.”

“It aroused the sad news that the legendary choreographer # SarojKhan was no longer,” added actor Akshay Kumar, who worked with him in various productions. “It made dance seem easy, as if anyone could dance, a huge loss for the industry. May his soul rest in peace.”

“Every time I know the choreography of the song, I opened an extra notch,” said singer Shreya Ghoshal. “You brought nuances, expressions, elegance on the screen with your heroes. The end of an era.”
