Philipp Sömmering (c. 1535[1] - 17 February 1575) was a German (Wolfenbüttel) alchemist and fraudster.
Together with Anna Maria Zieglerin and Schombach, Sömmering worked for Julius, Duke of Brunswick-Lüneburg, tasked with producing the philosopher's stone.
The three were put on trial in 1574 for multiple crimes, including the murder of a courier, attempted poisoning of Duchess Hedwig and copying keys to the Duke's chambers with the intent to steal some papers.
[2] Sömmering and Schombach were both burned with hot tongs repeatedly and then quartered alive.
Zieglerin's skin was pinched off and then she was burned alive while strapped to an iron stool.
