Johannes Lutma

Janus, or Johannes Lutma the elder (Emden, c. 1584 – Amsterdam, January 1669) was a well-known Dutch silversmith.

He was a pupil of Paulus van Vianen who was known for his auricular style in silver, so-called for its smooth, ear-like forms.

After spending time in Paris (c. 1615), Lutma came to Amsterdam in 1621 where he got engaged on 31 March 1623 to Mayken Roelants, and on 18 May 1638 to Saera de Bie.

Jan developed a distinct, if not very influential, technique of stipple engraving by making dots on the plate with a punch and hammer.

In the Amsterdam neighbourhood De Pijp, as well as Schoonhoven, there are streets named after him.
