Read about the events that shaped the Horniman family, the Museum and collections established by Frederick Horniman.

The Horniman Museum and Gardens is located in Forest Hill, South East London.

It first opened as the Surrey House Museum in 1890 in the Horniman family residence. In 1901 it changed its name to the Horniman Museum when it re-opened in a new purpose-built museum building.

The Horniman is named after Frederick Horniman, who inherited and ran his father’s business, Horniman’s Tea, and was elected as an MP for the Liberal Party in 1895.
