Melitta Brunner competed both in singles and pairs, and won World Championship medals in both events. She twice came second in the pairs event with Ludwig Wrede (1929 and 1930), and placed third individually in 1929 as well. Nationally, Brunner was always overshadowed by other skaters in the singles. She never won a national championship in this event but she was second in five consecutive years (1926-1930), twice behind Herma Planck-Szabo and three times behind Fritzi Burger. Her only national title came in 1930 in the pairs together with Ludwig Wrede after placing third the year before.
Following her active career, Brunner taught skating in Switzerland and Great Britain. There, she married a German skater, non-Olympian Paul Kreckow. After the war, she briefly toured Europe with ice shows, and eventually emigrated to the United States, where she kept skating and teaching until her death at age 96.
