Granville Pullen (1838-1926) had developed an interest of collecting relics from the past at an early age. Since 1870 he was a frequent visitor to the Honey Lake Valley to see his sister, Susan Goumaz. In 1901, he moved near Janesville and bought a ranch. In 1914, at the age of 76, he retired from ranching and bought a house in Janesville.
Not to be idle in retirement, he opened a small museum in Janesville to display his collection of curios. People fascinated by his collection began donating items to him. In 1920, Granville and his wife Mary, moved to Susanville and bought a home on South Roop Street. Next to his new home, he had a small concrete building built next to his for a museum. On June 18, 1921, he opened the museum to the public. When he passed away in 1926, and his wife kept the museum open for awhile, but she did not have the same passion as her husband. Over the years, she donated a portion of the collection to Lassen County. The items were displayed for a number of years in the Veteran’s building, and over time the collection slowly disappeared.
