Berthold Woltze (*August 24, 1829, in Havelberg; †November 29, 1896, in Weimar) was a German genre painter, portrait painter, and illustrator. Woltze was a professor at the Grand-Ducal Saxon Art School in Weimar. Between 1871 and 1878, he published numerous works in the magazine "Die Gartenlaube." His most famous work is considered to be "The Annoying Cavalier" (1874).

Woltze was known for his genre paintings that often depicted scenes from everyday life, highlighting social and emotional themes. His works are characterized by precise observation and fine detail. The scenes he painted often reflect the social and emotional realities of his time. "The Letter," the painting you showed, is a typical example of Woltze's ability to convey deeper emotional and social issues through seemingly simple everyday scenes.
