Heureka Z was born in 1960 out of the Holsteiner mare line 8145.
Under Hermann Schridde she was one of the most successful international jumpers in the period 1969-71, where she had many wins in Hamburg, Aachen, Bruxelles, Vienna, Berlin and Noerten-Hardenberg.
After having won the Grand Prix in Aachen and getting second place in the Hamburg Derby, she was sold to Leon Melchior, founder of the Stoeterij Zangersheide, who again could celebrate with her impressive success (for example winning the Grand Prix in Berlin) before making her a foundation mare in Zangersheide.
The following decades only can be highlighted as follows:
Male offspring: Heureka Z produced Goliath Z (by Graf Gotthard Z)- who sired Grosso Z, the producer of Goldfever- and the legendary Ahorn Z (by Alme Z), who for example sired Acord I, II, and III, Aktionaer and over 15 other approved sons.
Female offspring: Heureka Z left four daughters for breeding, which founded a whole dynasty of show jumpers:
The first daughter Argentina Z, by Alme Z (1977) is legendary for her crosses with Ramiro Z: Rebel I, II and III, Ratina Z, Roxan Z and Renomee Z. This three sisters left already a new generation of broodmares, which now prove their world class very actually: for example Ratina Z daughter Calipa Z with her son Chicago Z (new stallion at Stud in Zangersheide) or Roxan Z daughter Cayleigh Z with her second place in the World Championship for young horses, 6 year olds in 2002!
