Hugo Wetscherek is the founder of Inlibris. He started dealing in books while still at school – mostly as a runner between the Vienna flea market and the first district's antiquarian bookshops, a very active scene in the 1980s. Soon he applied for an apprenticeship at the most distinguished of them and subsequently trained for a year at Antiquariat Ch. M. Nebehay before studying art history at the University of Vienna. In 1993 he started his own business under the name of Inlibris KEG.

Christopher Frey was educated at Heidelberg and Vienna. After studying English literature and philosophy for a master's degree, he later took a doctorate in early modern history. He joined Inlibris in 2000 and serves as senior cataloguer in most fields, also overseeing daily operations.

Martin Peche studied German literature and philosophy in Vienna. After completing an MA thesis on Karl Kraus and Peter Altenberg and qualifying as a grammar school teacher, he joined Gilhofer in 2000 and subsequently Inlibris. Martin heads the autograph department, overseeing an inventory of more than 10,000 letters, manuscripts, and documents. He is a sworn and court-certified expert for the transcription of 18th to 20th century manuscripts. He is also responsible for procuring export licenses and for our communications with the Federal Monuments Authority.

Stefanie Schwaiger studied art history at the University of Vienna. Having taken a master's degree with a thesis on Baroque nativity scenes, she joined Inlibris in 2014. Steffi not only oversees as many as ten fair shipments a year, but is also responsible for accessioning all incoming acquisitions. She is also an experienced cataloguer and photographer.

Theresa Dellinger submitted a master's thesis on mediaeval manuscripts at the University of Vienna in 2017 and joined Inlibris as a cataloguer the same year.

Gerlinde Ottinger holds a doctoral degree from Vienna's University of Applied Arts. A cataloguer at Inlibris since 2017, she has also photographed most of Inlibris's new acquisitions for the web.

Laura Gazzoli studied Classics at the University of Virginia before taking her doctorate in Medieval Studies (Anglo-Saxon, Norse and Celtic) at the University of Cambridge. She relocated to Vienna in 2018, where she worked at the Austrian Academy of Sciences as a post-doctoral researcher. She has worked for Inlibris as a cataloguer since 2025. Her focus is on Latin and Germanic languages.

Tayssir Khalfallah holds an MA in International Relations from Budapest Business University. Leveraging a diverse background that includes acting and work as a social media manager, she brings a unique perspective to the firm. She joined Inlibris in 2025, where she works as a cataloguer with a focus on manuscripts in Arabic, Urdu, Persian, and Ottoman Turkish. She also manages the firm's social media.

Kelsey Lindinger joined Inlibris in 2025 with a background in archival work and archaeology. She previously worked in both municipal and academic archives in Canadian and Scottish contexts. She holds an MSc in Information and Library Studies from Robert Gordon University (Scotland) and a BA in North American Archaeology from Wilfrid Laurier University (Canada). She assists with fair shipments, incoming acquisitions, photography, and cataloguing.

Brigitte Wetscherek, Hugo's mother, is a certified management accountant. She has been in charge of keeping the books straight at Inlibris Gilhofer Nfg. from the very beginning. She is also responsible for tracking tax liabilities and for keeping the cash flow steady – a challenging task in a business in which buying is sometimes considered more fun than selling.
