He began to learn tennis at age 11, and in 1931 he moved to Prague for better training conditions.[9]

In singles, he was victorious at the Hungarian International Tennis Championships, upsetting Henner Henkel of Germany in the semifinal and Ignacy Tłoczyński of Poland in the final. He reached the doubles finals with Josef Caska.
In late 1935 and early 1936, Hecht and Menzel toured the Far East, which included a visit to Japan to participate in the Japanese National Championships, where Menzel lost in the final, and they lost in the doubles final as well, both times to title defender Jiro Yamagishi. From there, they sailed to India where they were the finalists at the East of India Championships. Arriving home, he was defeated in the Czechoslovakian International Championship match by British player Fred Perry. He was a second straight time finalist in Budapest.
