Who he was
He was born Friedrich Johannes Maximilian Barduleck in Dresden on 15 November 1846 — an only son, in a house that already smelled of metal. His father, Friedrich Wilhelm Barduleck, was a Dresden gold and silver engraver: the trade of cutting fine images into hard metal, backwards and in reverse relief, so that a stamp presses them out the right way round.
Max learned two things at once. From 1860 to 1865 he attended the Dresden Art Academy, and in the same years he served his engraving apprenticeship under his own father. Art in the morning, hard steel in the evening. It is an unusually complete training for the job he was about to get and never leave.
In 1865, at eighteen, he was taken on at the Royal Mint in Dresden. By 1867 he was the only engraver the mint had left, working under the title of assistant engraver. In 1871 the title caught up with the reality: he was appointed Royal Saxon Mint Engraver. He held that post until he retired in 1911.
Do the arithmetic and it is startling. From 1865 to 1911 — forty-six years — the great majority of Saxony's coin designs and dies came off one bench. He cut for four kings in succession: Johann, Albert, Georg, and Friedrich August III. If you own a Saxon coin from that span, the odds are very good that you are holding Barduleck's hand.
He never married. He died in Dresden on 7 October 1923, at seventy-six.
