C. van Doorn
Van Doorn was a fencer at Salle De Vos in The Hague of professor J. De Vos. She was one of the earliest female fencers in the Netherlands. Together with four other females of Salle De Vos (H. Luden, Beelaerts van Blokland, E. van den Berg and H. van den Berg) she went to London, United Kingdom for the 1911 England–Holland women's fencing competitions. In Londen they competed against female fencers of the Bertrands Fencing Academy. This was the first international fencing competition for Dutch women. Van Doorn was the best Dutch fencer. She won four of her five matches and won from among the 1908-1909 British champion Millicent Hall. However, the Dutch team lost from the British team. A week later, after coming back in the Netherlands, she had a match against Beelaerts van Blokland during a main fencing event in The Hague.
