The Soffer brothers' furniture and antiques store at Singerstraße 4 in Vienna’s 1st district, was founded by Jacques Wallis in 1867 and taken over by the brothers Arthur (Artur) and Siegmund (Sigmund) Soffer and Alexander Levai in 1908. After Levai left the company, Hans Soffer joined in 1922. Arthur, Siegmund and Hans Soffer were the sons of Isak Ignatz Soffer, a furniture dealer from Trebitsch in Bohemia, and his wife Eleonora (Eleonore, Lora), née Feigelstock, who had already been the owner of a furniture, antiques, gold and silverware shop in Vienna's city centre at the end of the 19th century. In 1936, Arthur Soffer had the old "Drachenhaus" demolished, and the architect Felix Augenfeld built a seven-storey residential and commercial building with showrooms on three floors. The company had three business licences: for trading in new furniture and home furnishings, for antiques and works of art, and for used goods, limited to furniture and home furnishings. Kurt Soffer, a son of Arthur Soffer, was the authorised signatory in 1938. A total of 14 people were employed in the company at the time, including other sons of the owners.

At the end of April 1938, Robert Möder became the provisional administrator of the company. He appeared at the company accompanied by SA men and threatened the owners with arrest and concentration camp. As Möder was not allowed to take over the business himself as he had hoped, he brought in Viktor Blahut, a veteran of the Nazi movement in Austria, although Blahut had neither the necessary qualifications nor funds. In a verbal agreement, Blahut arranged for the Soffer brothers to hand over the business to him for around RM 20,000, a fraction of its real value, payable in instalments. He had valued the warehouse together with Möder. As the VVSt initially did not agree to this purchase, Blahut intervened with the Gauleiter Odilo Globocnik, who in turn interceded in favour of Blahut with the head of the VVSt Walter Rafelsberger. In August 1938, he received preliminary authorisation for the acquisition. The balance sheet and accounts auditor Karl Sladek, who was commissioned by the VVSt to carry out an audit before the final authorisation was granted, pointed out the glaring disproportion between the value of the company and the purchase price. Nevertheless, Blahut received approval for the "Aryanisation", and after a new valuation by the architect and expert Franz Wilfert and an intervention with the Reich Minister of Economics, he managed to largely avoid his payment obligations.

Arthur Soffer did not survive the Shoah. He probably fled to Hungary and died there under unknown circumstances. After their escape, Siegmund and Hans Soffer settled with their families in the USA – Siegmund in Cleveland, Hans in New York – while Kurt Soffer returned to Vienna. As the People's Court had sentenced Viktor Blahut to several years in prison and to forfeiture of assets, the 2nd Restitution Act was applied. The company was restituted in 1949. In the same year, Siegmund, Hans and Kurt Soffer re-established a general partnership at the old location, which replaced the sole proprietorship that had been listed under the name Viktor Blahut since the "Aryanisation" and the company was re-entered in the commercial register in November as Brüder Soffer, Antike und moderne Raumkunst. Brüder Soffer was deleted from the commercial register in 1988.
