Anna Katharina Block (1642, Nuremberg – 1719, Regensburg), was a German Baroque flower painter.
According to Houbraken she was the daughter of the flower painter Johann Thomas Fischer who taught her to paint.[1] She was good at painting flowers in water colors and in oils, and taught the Duchess Anna Maria of Mecklenburg-Schwerin, the wife of the Duke August von Sachsen, and their daughters in Halle, Saxony-Anhalt in the 1660s.[1] She married the painter Benjamin Blok in 1664 and was still alive when Joachim von Sandrart was writing his Teutsche Academie, which is where Houbraken took his data from.[1]
According to the RKD she was the daughter and pupil of Johann Thomas Fischer and married Benjamin Block.[2]
