 With his colleague Robert Boylestad at Queensborough College, they were the authors of many fundamental publications on electronic devices and circuits.Their seminal work "Electronic Devices and Circuit Theory" is a university level text that is currently in its 9th edition (2005) and which was initially published in 1972.While there are many other texts in the field, this one has remained a staple of scientific educators throughout the modern period of electronics and computer revolution, and during the emergence of ubiquitous Integrated Circuits and Computers.
