Max Kadel, Developer

IMG_2981Max is a developer with over seven years of experience in academic and museum libraries, including at the Metropolitan Museum of Art, the Frick Collection, and Westminster Choir College. He has an MSLIS from the School of Library and Information Science at Pratt Institute and a Master of Music in Musicology from the University of North Carolina at Chapel Hill. When not working, he enjoys playing the viola da gamba, an instrument originally popularized during the Renaissance. These seemingly disparate pursuits are linked by a curiosity about how changing the medium of communication changes the individualized human experience of that communication, whether the shift is from physical to digitized books, editing informant stories in folklore, or transcribing Renaissance music into modern notation.
