Adjoining the Dressing Room is the Secretary's Room; it was fitted with a mezzanine for the use of Paul I's personal attendant. As it belonged to the suite of state apartments, the Secretary's Room was furnished in mahogany. The furniture, with brass fillets, was of the type introduced by the brothers Jacob (the sons of Georges Jacob), which gained wide popularity towards the close of the eighteenth century. Following Western European fashions, St Petersburg cabinet-makers produced a great many variants of this type which came to be associated with the name of Jacob.
