Oscar became an important figure in Chico. He ran a hospital for some time since none existed and was very concerned with public health. He was a member of the California Board of Public Health, which enforced sanitary and hygienic regulations. He also helped establish the Bureau of Vital Statistics and also helped pass the California Pure Food and Drug Act in 1907. He also traveled to the Panama Canal to study malaria and yellow fever prevention methods. Oscar passed away in 1926. The house remained in the family until Oscar's oldest daughter, Angelina, died in 1976. The City of Chico then acquired the property.
