In 1839 Herman J. Kähler immigrated to Næstved from Northern Germany. Shortly after his arrival, he started his own pottery in Næstved, where it all began.
Kähler was a trained potter, and staying true to the old traditions, he stuck to production of articles for everyday use as milk dishes, soup pails, jam jars etc. However, he was best known for his production of all-night burners.
Kähler ran the company from 1839 to 1872. During that period he fathered seven children.
