In 1869 Rudolph Knoblauch immigrated to San Francisco after he spent twenty years as a chef on a ship. He left San Francisco for Denver in 1881 where he bought 160 acres where the present day Civic Center stands. There he bought a cafe where he met his wife, Katherine Rausch. The two married and moved to Del Norte where they eventually bought 160 acres west of town and bought another cafe.
By 1900 Rudolph Sr. had acquired over 700 acres. As the years went by Rudolph Sr. would sell different portions of the land to his children. Rudolph Jr. eventually married Ina Bell Wills on Aug. 17 1922. Their son Melvin Rudolph Knoblauch was born a year later. Unfortunately, Rudolph Jr. died of a heart attack leaving Ina a widow with a 3 year old son. Ina then went to work in town and leased the farm for a few years. In 1930, Ina married Carroll Wetherill who took care of the ranch. The family then acquired horses and cattle from older relatives to add to the ranch. As Melvin got older, he would begin to take care of the ranch.
Melvin married Irene Marguerites on July 12, 1943 and on May, 2nd 1944 Marcia Joan Knoblauch was born. Melvin served a couple years in the Army Air Corp during World War II before returning home to run the ranch. Melvin Curtis Knoblauch was born on September 30, 1949. Curtis married Jennifer Ann Larson in 1969, and after finishing college, the two moved back to the ranch to take over farming with Melvin. The ranch would eventually become a dairy operation. Today the ranch has milk cows and goats, and the family produces cheese and gives tours of the dairy farm.
