Antonie Sommer, known as Toni, was born on 5 September 1883 in Czernowitz (now Chernivtsi, Ukraine), the capital of Bukovina in the Austro-Hungarian Empire. Just before the turn of the century, she moved with her husband Naftalin Plattring, a merchant, whom she had met in Austria, to the island Cebu in the Philippines. Naftalin planned to set up a pearl-trading business there. While living in Cebu, the couple had five children: their sons Friedrich and Adolf, born in 1902 and 1904, and their daughters Fanny, Flora and Jeanette, born in 1911, 1913 and 1915, respectively.
Around 1922, the family returned to Germany, where they moved to the Marienfelde district of Berlin-Tempelhof. Naftalin Plattring acquired a property at Kirchstraße 85. Two years later he built a house on the site opposite at Kirchstraße 84. The Plattrings also owned a plot of land in Schöneiche outside Berlin.
In 1922 Naftalin Plattring established a bottle-top factory with his business partner Rudolf Stern, which he was forced to sell in 1936. Between 1936 and 1939, all five of the Plattrings’ children managed to emigrate abroad. Antonie and Naftalin Plattring themselves apparently felt too old to start a new life abroad.
In 1938 the Plattrings were forced to sell their house at Kirchstraße 84 to the factory-owner Wilhelm Brösel, who also acquired the house opposite. They also had to sell their land in Schöneiche. In December 1940 they had to vacate their home at Kirchstraße 84, which they had lately rented, for a sales representative named Otto Ebert. They moved into an apartment at Uhlandstraße 182 in Berlin-Charlottenburg as subtenants, occupying one room.
On 20 December 1941, the Plattrings and their landlady Ella Rosenbaum received deportation notices. The mandatory declaration of assets, completed before deportation, shows that by that time, Antonie Plattring owned merely 1 table cloth, 2 serviettes, 2 towels, 2 pairs of stockings and 2 sets of underwear. On 13 January 1942, Antonie Plattring and her husband were sent on the “8th transport” along with 1032 others to the Riga ghetto. No more was seen or heard of them again.
