From 1930 to 1932 Fritz studied at Hansische Hochschule für Bildende Künste in Hamburg, Germany.
From 1917 to 1926 Lachmund studied at Volksschule. In 1926 he became a student of Industrial Arts School. In nine years he graduated from this school. From 1930 to 1932 Lachmund attended Landeskunstschule, a regional art school now called Hansische Hochschule für Bildende Künste in Hamburg, Germany.
Aside from his photographic activities, Lachmund frequently lectures on the history of Hamburg and its surrounding area, organizes exhibitions, and serves, more or less, as the foundation for contemporary and historical photography in his native area.
His personal work centers again on his native country, with particular attention to Hamburg, including portraits of public life and genre scenes. In his photographic collection, he has approximately 200,000 views of the city and its surrounding areas, some images dating back to 1843.
