In the early 1860's, German native Heinrich "Henry" Twisselman and his four brothers arrived into the San Francisco Bay as merchant seamen aboard a Danish whaling ship. After meeting his wife Elizabeth "Lizzie" Meng, a Switzerland native, the couple moved to San Luis Obispo in the late 1870's to establish Chorro Dairy, where Cal Poly State University now sits. Unfortunately, Henry passed away some short six years later of tuberculosis, leaving Lizzie and her five children. In 1884, Lizzie moved to join her family's homestead in the hills above Cholame farming grain and raising livestock, establishing what now remains Twisselman Ranch and making her one of the first pioneers of the California frontier.
