Ivan Herman graduated as mathematician at the Eötvös Loránd University of Budapest, Hungary, in 1979. After a brief scholarship at the Université Paris VI he joined the Hungarian research institute in computer science (SZTAKI) where he worked for 6 years (and turned into a computer scientist…). He left Hungary in 1986 and, after a few years in industry in Munich, Germany, he joined the Centre Mathematics & Computer Sciences (CWI) in Amsterdam where he had had a tenure position between 1988 and the year of his retirement, i.e., in 2021. He received a PhD degree in Computer Science in 1989 at the University of Leiden, in the Netherlands.

He joined the W3C Permanent Staff in January 2001 while maintaining his position at CWI and has continued to stay on the staff, albeit with reduced hours, after his retirement. As a W3C staff member, he served as Head of Offices until June 2006, then as Semantic Web Activity Lead until December 2013. He is the Publishing@W3C Technical Lead, as well as the W3C staff representative for the work on EPUB 3, Audiobooks, Decentralized Identities, and Verifiable Credentials. He was also member of the Strategy, as well as the Technical & Architecture teams of W3C until 2021.

Before joining W3C he worked in different areas (distributed and dataflow programming, language design, system programming), but he spent most of his research years in computer graphics and information visualization. He also participated in various graphics-related ISO standardization activities and software developments. See his professional web site for further details, including his list of publications, presentations, and various social activities.

Ralph joined W3C in January 1997, to focus on the Privacy and Demographics project. As that project (now called P3P) was starting, Ralph also started the Metadata project. The Resource Description Framework became a full-time responsibility when the Metadata Activity turned into the Semantic Web Activity. In 2007 Ralph became the leader of the Technology and Society Domain and in 2009 was appointed Acting Chief Operating Officer. As of 2010 the 'acting' qualifier was removed. Then in 2022 Ralph was appointed as Interim Chief Executive Officer of the new W3C, Inc. Ralph came to W3C from the X Consortium, where he was Technical Director for the X Window System. Ralph brings to W3C both a systems background and an application background. Long involved with the X Window System, Ralph was one of the architects of the Xt Intrinsics (user interface) toolkit. Prior to joining the X Consortium, Ralph was a software engineer for Digital Equipment Corporation in their Office Systems Advanced Development Group. There he worked on information filtering tools (software agents) and computer-supported cooperative work tools. Before that, Ralph was in Digital's Corporate Research Group working at MIT Project Athena. Ralph holds a BS in Physics and Mathematics from Carnegie-Mellon University. Ralph's interests are in applications of Web technologies to support human-human interaction, especially over time and distance.
