2 Lt. Wacław Loth “Kupiec”, “Karol” was born 10 May 1906 in Warsaw. He was the son of a pastor of the Varsovian parish in the Holy Trinity Evangelical Church of the Augsburg Confession. He finished Mikołaj Rej high school, as well as the Warsaw School of Economics. He worked as an official in the “Fryderyk Puls i S-ka” cosmetics company. He was a sportsman, playing for the Polonia Warszawa soccer team. Loth took part in the fight actions of September 1939. From the end of 1939, he was a part of the Union of Armed Struggle, later Home Army (ZWK/AK). In the time of the occupation, Loth lived at 22/20 Jasna Street. For several days before the Uprising, he entrusted his apartment to the disposition of Cl. Antoni Chruściel „Monter”, the commandant of the Warsaw District in the Home Army. During the Uprising, Loth commanded a special department in acquiring air drops. After the capitulation, he was sent to Stalag X B in Sandbostel. In 1945, he returned to Poland and settled in Radom with his family, where he worked as the director of the Sales Office in bath ceramics. Loth died 16 January 1950 in Warsaw.

• Wacław Loth photographed the entire duration of the Uprising, mainly in the areas of his apartment (20 Jasna Street), the areas of his unit in the southern City Centre, and random shots taken in other places (ex. the Powiśle Power Plant). The photo documentation of the Uprising was taken with a Kodak Vollenda folding camera, on 6x9 cm format film. Upon leaving Warsaw, Loth entrusted 8 rolls of undeveloped film to his son, Roman, who later developed them in a small photo laboratory in Radom. The collection consists of 64 photographs. They present images of the destroyed buildings of the City Centre, insurgents, barricades, outside Holy Masses, stationed men on the rooftops waiting for air drops, as well as photographs of his family and friends.
