8. Patronage

He corresponded with Duke Albrecht of Prussia (1541-1544) and made instruments for him. Albrecht overpaid him 60 gulden for an instrument, Hartmann promised to make him a sundial for the 60 gulden surplus, and this initiated their correspondence. In their correspondence, Hartmann mentioned visits from King Ferdinand, and the apostolic envoy and the Venetian orarier, who commissioned various pieces.
He also had commissions from King Ferdinand of Bohemia and Hungary, who invited him to visit three times. Ferdinand gave him a cup worth 43 gulden once, and another cup worth 60 gulden six years later. Hartmann also received commissions from Ferdinand's consort.
He corresponded with, and received commissions from, Duke Ottheinrich, who sent him a 1517 box wood sundial and a commission for two ivory sundials, a brass astrolabe, and a brass armillary sphere.
He also corresponded with, and received commissions from Melanchton.
With a goldsmith, probably Hans or Elias Lenker, he produced a "Instrumentenkaestchin" for Duke Emanuel Philibert of Savoy, the cousin of Emperor Charles V.
