Schlosser
A German occupational surname meaning a locksmith or metalworker who made and repaired locks.
The #4,892 most common surname in the United States (2010 Census) — about 1 in every 42,863 Americans shares it.
Etymology
Schlosser comes from German Schloss, meaning “lock” or “castle,” plus the agent suffix -er, “one who works with.” In surname use, it referred especially to a locksmith or a skilled metalworker associated with locks and fine mechanical work. Older German sources also connect it with Kleinschmied, a “small” or precision smith.
History
The name is common in German-speaking areas and also appears in variant forms such as Schlösser and, in older records, related forms like Schlotthauer or Schlosser-derived spellings in dialect areas. It travelled with German migration, so it is found in North America and elsewhere in German diaspora communities. Nineteenth- and early-twentieth-century surname writers consistently treated it as an occupational name rather than a place-name.

Fun fact
Some older German surname discussions gloss Schlosser as a finer specialist than an ordinary smith, closer to a precision metalworker than a heavy forge smith.
