In the 18th century, this place was a summer paradise almost completely surrounded by water. At the time, it was called Ryttarudden. Here, in 1764, Councilor Carl Gustaf Tessin arranged an exceptional midsummer party for the court and several distinguished guests, which was long talked about both near and far. It is believed that the current name Täcka Udden came from this midsummer party, where “täcka” is an old Swedish word for “beautiful”.
The French Renaissance-style villa was built in 1870 as a summer house for the punch manufacturer and Belgian Consul General in Stockholm Fredrik Cederlund. In 1888 it was bought by Knut Agathon Wallenberg and has stayed with the family ever since. Summer residence at first, it has become the home of several Wallenberg generations. Since 1958, the house has been used as a place of representation for Wallenberg’s companies SEB and Investor.
There is hardly a single person in Sweden who hasn’t heard of the Wallenbergs, the family of bankers, industrialists, politicians and diplomats. One of the most famous internationally was Raoul Wallenberg, a diplomat who worked in Budapest during World War II and rescued tens of thousands of Jews from the Holocaust.
The Wallenbergs are present in most large Swedish industrial groups, including Ericsson, Electrolux, ABB, SAAB, SAS Group, Atlas Copco. In the 1970s, the Wallenberg family businesses employed 40% of Sweden's industrial workforce and represented 40% of the total worth of the Stockholm stock market.
It was Knut Agathon’s father André Oscar Wallenberg who in 1856 founded Stockholms Enskilda Bank, which later became the banking giant Skandinaviska Enskilda Banken (SEB). Knut Agathon was the CEO of the bank from 1886 until 1911.
Today, the fifth generation of Wallenbergs is taking care of the house and the family business empire. They keep a remarkably low-key public profile, deliberately avoiding conspicuous demonstration of wealth. The family motto is Esse, non Videri (Latin for "To be, not to be seen").
