A statement from the Hampstead music studio expressed “heartfelt condolences” to Sir George’s family and described the music legend as “wonderful”.

Is said: “We would like to thank George for creating Air Studios, which is a truly fitting legacy for a wonderful man who contributed so much to the music industry over many many years.”

The studio also tweeted: “Sir George - so very much loved by all of us. An amazing man. An inspiration to so many. We will miss you.”

The legendary producer of The Beatles, often described as the fifth member of the band, founded Air Studios in 1969 and relocated it to Lyndhurst Hall, Hampstead, in 1991.

Sir George entered the music industry in 1955 and throughout his career produced every Beatles track recorded, 30 UK number one singles, was awarded five Grammys and created his own publishing company, as well as setting up the studios.

He received a knighthood in 1996 and in 1999 he was inducted into the Rock and Roll Hall of Fame.

After Sir George’s death was announced on Tuesday night, his son Giles Martin tweeted: “RIP dad. I love you. I’m so proud to have been your son. I’ll miss you more than words can say. Thank you for the all times we had together.”

Paul McCartney published a moving tribute to his friend and colleague, whom he described as being “like a second father to me”.

He wrote: “I’m so sad to hear the news of the passing of dear George Martin. From the day that he gave The Beatles our first recording contract, to the last time I saw him, he was the most generous, intelligent and musical person I’ve ever had the pleasure to know.

“I am proud to have known such a fine gentleman with such a keen sense of humour, who had the ability to poke fun at himself. The world has lost a truly great man who left an indelible mark on my soul and the history of British music.”

The “fifth Beatle” has been celebrated by the likes of Liam Gallagher, Boy George, Dame Shirley Bassey and Sir Roger Moor who tweeted “how very sad to wake to the news Sir George Martin has left us. He made my first Bond film sound brilliant!”

Sir George’s family have thanked “everyone for their thoughts, prayers and messages of support”
