Dr. Danny B. Lange (born 1962) is Software Architect in the Unlimited Potential Group (UPG) at Microsoft where he is the principal architect behind the OneApp  mobile phone platform. Prior to UPG, he was the architect in the Search Group responsible for Mobile Search. He is widely known for his invention of the Java Aglet, a lightweight mobile agent for the Java programming environment. In 2000, IBM Research turned the Java Aglets project into an Open Source project. He has authored the two most frequently cited works on mobile agent technology. In addition to his software agent work, he has also made significant contributions in the areas of hypertext technology, object-oriented database modeling, and Design Pattern visualization techniques.
Danny is also recognized in the industry as a leading proponent of the VoiceXML standard and as an expert in speech recognition systems. As co-founder of Vocomo – 2001 to 2005 – he built one of the best Interactive Voice Response (IVR) systems in the world. This 100% Java-based VoiceXML system allows users to extend existing or new Web applications to be accessible by any phone.
As CTO of Silicon Valley’s legendary General Magic, Inc., Danny was instrumental in building the architecture for its industry-leading voice response service architecture. His early work with General Magic resulted in the invention of software agents, which monitor and act on Web content on behalf of a user, and when necessary, interacts with the user via voice. Through his work on General Motor’s OnStar Virtual Advisor, Danny provided the foundation for the development of one of the largest consumer services in the voice market. Prior to joining General Magic, Dr. Lange was Visiting Scientist at IBM Tokyo Research Laboratory from 1993 to 1997. He has also been Visiting Researcher at Tokyo University and a consultant for Nissho Electronics in Tokyo. From 1987 to 1992, Danny was Software Architect at Brüel & Kjær A/S in Nærum, Denmark, where he led development of a pioneering network-based distributed hypertext system. He developed his first network-based hypertext browser in 1988 and pioneered the concept of Web CGI in 1992/93. Danny wrote his first program for CP/M on a Canon micro computer in 1980. He also wrote a compiler for Canon Basic based on the Motorola 6809 CPU.
Danny is a native of the Kingdom of Denmark. He holds MS and Ph.D. degrees in Computer Science from the Technical University of Denmark. He is a member of ACM and IEEE Computer Society. He has several patents to his credit, has presented his work at leading conferences, published articles in many journals.
