Hedwig "Hedy" Bienenfeld, also known after marriage as Hedy Wertheimer was an Austrian Olympic swimmer. She won a bronze medal in the 200m breaststroke at the 1927 European Aquatics Championships. She competed in the same discipline at the 1928 Summer Olympics. At the 1932 Maccabiah Games and 1935 Maccabiah Games in Mandatory Palestine, she won a combined five gold medals, one silver medal, and one bronze medal in swimming.

The 1st Maccabiah was the first edition of the Maccabiah, which was held in Mandatory Palestine from March 28 to April 2, 1932. The games were in commemoration of the 1800th anniversary of the Bar Kokhba revolt, a major rebellion by the Jews of Judaea Province against the Roman Empire. Despite many obstacles and setbacks, the first Maccabiah was regarded as a great success. Poland led the scoreboard, the United States was second, and Austria was third.
