Bernard Stanley "Acker" Bilk MBE (28 January 1929 – 2 November 2014) was an English clarinettist and vocalist known for his trademark goatee, bowler hat, striped waistcoat and breathy, vibrato-rich, lower-register clarinet style.

Bilk's 1962 instrumental tune "Stranger on the Shore" became the UK's biggest selling single of 1962 where it remained in the UK charts for more than 50 weeks, peaking at number two, and was the first No. 1 single in the United States by a British artist in the era of the modern Billboard Hot 100 pop chart.
