Gerolfingen village had a harbor on the lake and was a local trading and fishing center. The residents of Täuffelen grew crops, cared for vineyards on the hill below the church and fished in the lake. The first industrial factory opened in Täuffelen in 1846 and began to change the character of the village. This first factory, which manufactured watch and clock parts, was followed by several other factories. The Jura water correction projects and the construction of the Aarberg-Hagneck Canal between 1868 and 1880 opened up new land around the villages and removed the threat of flooding. In 1916 the growing village was connected to the Biel-Täuffelen-Ins (BTI) railroad. In 1944 the BTI established their headquarters in Täuffelen. While industry grew in the village, cherry orchards flourished in the farm land around it. In 1950 a secondary school opened in the municipality, which brought in students from surrounding communities.
