Bengt Feldreich was a trained folk teacher and began his career teaching in the days and doing international programs for Radio Service, now Sweden's Radio, in the evenings. In 1955 he got a job on television - which was then brand new - and stayed there for 30 years. Among other things, he led programs such as "Away or Double - The Ten Thousand Crown Question" and "Snillen Speculates".
- I want to be remembered as the reporter who always stood on the side of the viewer and listener. Professors were used to being contradictory, but I was strict on them until they understood that they had to understand. It was gratifying to translate knowledge, Bengt Feldreich said in an interview with TT at the 90th anniversary.
He was TV's first Christmas host in 1959 and continued with it until he turned over to his friend Arne Weise in 1972. Bengt Feldreich was the voice of the classic Christmas program "Kalle Duck and his friends wish Merry Christmas", where he also made Benjamin Syrsa's voice and sang "Do you see the star in the blue". He himself thought that the Disney program was getting too big, yet he continued to read ads for newly released Disney films after retirement.
He became an honorary doctor at Linköping University in 1975 and received the Royal Swedish Academy of Technology's great prize in 1984. Bengt Feldreich died in the suites of pneumonia and turned 94 years old.
