Jacoba Adriana Hollestelle (16 January 1937 – 7 April 2002), known professionally as Conny Vandenbos, was a popular Dutch singer. She had her first radio hit in 1966 and continued to make hit recordings throughout the 1970s. She represented the Netherlands in the Eurovision Song Contest 1965 with the song "'t Is genoeg".
Catharina van Rennes (2 August 1858, Utrecht – 23 September 1940, Amsterdam) was a Dutch music educator, soprano singer and composer.
Van Rennes was the daughter of Jan van Rennes and Marianna Josepha de Jong. Among her tutors were Richard Hol and Johan Messchaert. She made a career as a singer in oratorios and was highly praised for her interpretations of Schumann Lieder. She was also known for vocal compositions. She composed and conducted a cantata for The International Alliance meeting of the women's suffrage movement held in Amsterdam in 1909 which was performed by the Queen's Royal Band.Van Rennes established her own singing school and developed her own teaching technique. Like her contemporary Hendrika Tussenbroek, she is remembered today for some popular Dutch children's songs such as "Drie kleine kleutertjes die zaten op een hek" (Three little toddlers were sitting on a fence), a translation of a Kate Greenaway verse, and "Madonnakindje" (Madonna child) as well as a religious song Kind'ren van één vader" (Children of one Father).
Julia Bertha Culp (6 October 1880 – 13 October 1970), the "Dutch nightingale", was an internationally celebrated mezzo-soprano in the years 1901–1919.
"You might describe Julia Culp as a connoisseur’s singer," Michael Oliver wrote in the International Opera Collector in 2000. "Her voice was not large, her compass not wide. She never sang in opera; striking dramatic gesture were not her line. What she excelled in were the singer’s rather than the vocal actress’s virtues: sustained legato line, remarkable breath control, subtle colour, immaculate care for words…. But ‘connoisseur’s singer’ does not mean that only connoisseurs can appreciate her; one becomes a connoisseur by listening to her."
