Couldn't determine a fitting category. You provided a title that combines three sentences related to a serial killer, but there is no mention of technology, programming, or any other categories listed. The title seems to be a translation of three sentences describing an individual, which doesn't fit into the prioritized list of categories.

Since Georgy Orlov-Davydovsky is not exclusively associated with a specific known category from the provided prioritized list, the most relevant category that fits him is "Education & Learning" and more specific to the context, "Technology & Programming" due to Georgy being an 18th-century keyboard composer and a notable figure in the creation of the 'Clavichord.'
