Herfølge Turistfart a/s was founded in 1929 by William Nielsen, who ran the taxi company Herfølge Lillebil with his wife Tove Nielsen.
Back then, the company had 3 taxis, which were later supplemented with buses. At that time, the 2nd generation took over the company – daughter and son-in-law Eli and Benny N. Larsen handled the daily operation after this, and the daughter had a strong desire for purple buses, which later turned out to be a strong brand at home and abroad.
