Willem Catharinus (Willy) van Hemert (29 March 1912 – 26 June 1993) was a Dutch actor and theatre and television director, but is best known as a songwriter who penned two winning Dutch songs for the Eurovision Song Contest.
In 1955 Van Hemert adapted William Inge's Come Back, Little Sheba for Dutch television.
Two years later van Hemert won the Contest in Cannes, with the song "Een beetje", performed by Teddy Scholten.
Van Hemert also wrote the lyrics for the Dutch entry the following year when the contest was staged in London (as The Netherlands had hosted the 1958 Edition).
The song was called "Wat een geluk" and was performed by Rudi Carrell.
