Aristid received his education at the Lutheran High School in Aszód and at the Franz Liszt Academy of Music in Budapest.
Würtzler's last performance in Hungary took place on 22 November 1956, in the Opera House when he was substituting for the bedridden Rékai.
For a time he lived in a house occupied by prostitutes, who kindly loaned him the money to buy his first harp.
Leonard Bernstein (musical director) auditioned him; Aristid played, inter alia, Smetana's Vltava, Debussy's Prelude to the Afternoon of a Faun, and Bartók's Concerto for (Piano and) Orchestra.
He invited famous foreign musicians to join his master classes, e.g. the above-mentioned Pierre Jamet; Hans Joachim Zingel, the renowned expert of harp-literature from Cologne; the Belgian and Soviet harpists Mireille Flour and Vera Dulova; and Khachaturian, the Armenian composer.
In 1969, Würtzler organized the first international harp competition ever held in the United States thought his primacy is contested by some.
With the ensemble and also as a soloist Würtzler performed in over sixty countries, made numerous compact discs and had several invitations to play at the White House during the Carter, Reagan, Bush and Clinton administrations.
In his other pursuits, Würtzler served as a member of the Jury at the Harp Contests in Israel, Switzerland and Italy.
In spite of his international acclaim, in his heart Würtzler remained passionately devoted to his native Hungary and he returned regularly from the mid-seventies.
He established annual Harp Master Classes and gave several concerts in Budapest, in Szombathely and in the Helikon Castle in Keszthely.
