Martin von Wahrendorff (1789 – 1861) was a Swedish diplomat and inventor.

[1] His father Anders von Wahrendorff was the owner of the gun foundry at Åker.

The first breech loaded Wahrendorff gun was manufactured at Åker in 1840.

The two then started experimenting with pointed elongated lead-coated projectiles fired from rifled, breech loading, guns of Wahrendorff's design.

In 1854 the Swedish Army adopted three different types of smooth bored breech loaded Wahrendorff guns, in calibers from 155 to 226 mm.
