European wand maker who made Krum’s wand (GF18) and retired from business in the late 1980s (DH8). At one time he owned the Elder Wand and bragged about it, but Gindelwald stole it from him in the early 1940s. When Voldemort was tracking the Wand in September of 1997, he looked for Gregorovitch. The wandmaker no longer lived at the same address, and Voldemort murdered the woman and children living there out of spite; this may have been Gregorovitch’s family (DH12). When Voldemort finally tracked Gregorovitch down, he tortured him, entered his mind to see that the Wand had in fact been stolen by a fair-haired, merry thief, then killed the wandmaker (DH14). Gregorovitch was a heavy-set man with white beard and hair.
On the website HarryPotterWallArt.com, Gregorovitch's first name is given as Mykew. However, this is strictly non-canon.
