Gehnäll Persson (21 August 1910 – 16 July 1976) was a Swedish Army fanjunkare and equestrian.
[1] He competed in dressage at the 1948, 1952 and 1956 Olympics and won team gold medals in 1952 and 1956; he finished fourth individually in 1956.
[2][3] At the 1948 Olympics the Swedish team won with a wide margin and received gold medals.
The team was disqualified in 1949 after it was found that Persson was only a fanjunkare, temporarily promoted to the rank of lieutenant specifically to circumvent the "Officers and Gentlemen only" eligibility rule at the time.
[4] Later that year the International Federation for Equestrian Sports relaxed its eligibility rule to allow non-commissioned ranks (and women) to compete.
