Maier-Labergo was a three-time German men's champion in figure skating between 1930 and 1942.
At club level, he represented Münchner EV (based in Munich), where his coach was Ludwig Niedermayer.
After Maier-Labergo's amateur career he became a professional skater and skating coach in Winnipeg, Manitoba, Canada, where he was known as Leopold Labergo.
One of his students was Mary Rose Thacker, a future Canadian and North American champion, while others included Fraser Sweatman and Audrey Garland, who skated for Canada at the 1936 Winter Olympics.
Maier-Labergo died in Winnipeg in 1939, aged 32, at the Misericordia Health Centre.
