German SD establishment in which, according to German spy chief Walter Schellenberg, "important visitors from other countries could be 'entertained' in a discreet atmosphere and...offered seductive feminine companionship. In such an atmosphere the most rigid diplomatic might be induced to unbend and reveal useful information."

Salon Kitty was set up in a large house in a fashionable district of Berlin. It is described in The Schellenberg Memoirs (1956): Double walls were built for the incorporation of microphones. These were connected by automatic transmission to tape recorders which would record every word spoken throughout the house. Three of our department's technical experts, bound by oath, were put in charge of his apparatus. The ostensible owner of the house was provided with the necessary domestic and catering staff for the establishment to be able to offer the best service, food, and drink.

The women of the establishment were recruited from "the most highly qualified and cultivated ladies of the demi-monde." And, according to Schellenberg, "quite a few ladies from the upper crust of German society were only too willing to serve their country in this manner."

The salon was highly successful in garnering secrets from its clients, mostly foreign diplomats. Occasionally it was used by Nazi leaders, particularly Reinhard Heydrich, when, of course, the microphones were turned off.
