Irvine Robert Laurie Kennedy (he used Laurie, later dropping the final 'e') was born in Randwick, a suburb of Sydney, to an English-born father and native-born mother. He studied with Herbert Walenn at the Royal College of Music, London, and Paul Brummer in Vienna. Dame Nellie Melba noticed him and encouraged him to undertake further studies in the United States. He made his mark there in the 1920s, where he was principal cellist with the New York Philharmonic, at the personal invitation of Arturo Toscanini. He played chamber music with performers such as Arthur Rubinstein and Jascha Heifetz. In the United Kingdom he played in a noted piano quartet called the Chamber Music Players with Albert Sammons, Lionel Tertis and William Murdoch. He also appeared with the tenor John McCormack for a number of years, and appears on record accompanying McCormack.
He became principal cellist with Sir Adrian Boult's BBC Symphony Orchestra at its inception in 1929 and played with them until 1935. His cello can be heard in the slow movement of Boult’s 1935 recording of the Brahms 2nd Piano Concerto with Artur Schnabel. He recorded music with Fritz Kreisler and William Primrose, including Kreisler’s String Quartet in A minor in 1935 with members of the London String Quartet. He recorded Edgar Bainton’s Cello Sonata. After Felix Salmond and Guilhermina Suggia turned it down, Lauri Kennedy was engaged to premiere Frank Bridge’s Oration for cello and orchestra, but withdrew during rehearsals. He also became a professor at the Royal College of Music.
His wife Dorothy Kennedy (née McBride) was a pianist who also accompanied John McCormack and taught the children of Enrico Caruso. Lauri and Dorothy appeared together in some recordings,  including Edison 80683, Popper: Hungarian Rhapsody.
They made a highly successful tour of Australia in 1938. They then went to the United States again, where Lauri joined Toscanini's NBC Symphony Orchestra. He relocated to Hollywood and his playing is heard on a number of films, including Walt Disney's Fantasia.
In 1944 they returned to Australia permanently. They bought hotels in Taree and Sydney, and Lauri taught at music camps. Australian singers he accompanied included Stella Power. Lauri later taught cello at the Canberra School of Music in 1966, resigning after only one year due to poor health. His private students include John Painter, himself a future Director of the Canberra School of Music.
