Fernando Heydrich Klein (26 January 1827 – April 1, 1903) was a German businessman, politician, engineer and sculptor who lived in Matanzas, Cuba.

Builder of the Aqueduct of Matanzas, he was politically engaged, playing a significant role during the Ten Years' War in Cuba.

With his son Alfredo and his company Heydrich and Raffoler & Cie, he requested the patent, which he finally got after a long dispute and thus began a new kind of production in Cuba.

He received the explicit consent from Otto von Bismarck through a telegram to Consul Luis Will, in 1869, under the condition of preserving neutrality.
