The establishment of guest houses at American River in the early part of the last century were the forerunner of today's tourism industry on Kangaroo Island. Ryberg, Lierich, and Linnett, are names synonymous with the development of tourism at American River.
Nils Ryberg, a Swedish born immigrant, settled at American River in 1884, and ten years later built the original "Ryberg House" on the site of the present Kangaroo Island Lodge, exclusively for tourist accommodation.
Ryberg added to the building over several years, before selling to John and Valerie Linnett in 1913. Ryberg House was completely rebuilt in 1928, and remains today. Fishing trips were an integral part of the business, with three boats, Warrigal, Linnette and Linnette 2 comprising the fleet which operated until 1985.
The business was operated until John Linnett's death in 1955, after which time his four sons, Keith, Lionel, Leon and Gordon continued under the name of Linnetts Pleasure Resort.
Leon Linnett assumed sole proprietorship in 1971, expanding the resort with the erection of several new wings and refurbishing the reception, administration and restaurant areas in 1980, when the resort became known as Linnetts Island Club.
Leon Linnett sold the property in the late 1990s to an Adelaide-based consortium that trades under the name Kangaroo Island Lodge.
