Hermann Weiland was from Mannheim, Germany but some extra citizenships allowed him to ride for Croatia at the 1992 Olympics in Barcelona and at two European Championships, in Gijon in 1993 and St. Gallen in 1995. Placing only 18th at the 1987 German Championships in his hometown, he had no chance to make the German Olympic team, so he initially competed for Guam. But he had to live there for 1½ years to get his citizenship card, so he opted for Croatia instead. However, at the 1992 Olympic Opening Ceremony, he marched with Guam, preferring to come into the Olympic Stadium in his grass skirt, wearing the Guam uniform.
Educated as a landscape architect and working in horticulture construction, he later became the main German golf course designer, founding Golfanlagen Weiland GmbH in 1996. He also founded the concept of so-called “rotation golf courses,” a new concept in Germany, which means that the members of the Weiland-group earn the right to play golf on every course belonging to this group.
