I am an engineer with a Bachelor of Science Degree in Computer Science from the School of Engineering and Computer Science at California State University, Northridge. I am a Software Engineer / Computer Scientist by profession. I have worked for the U.S. aerospace and defense industry, as well as the U.S. law enforcement industry writing all types of software.

I have been in the business of researching U.S. Combat helmets since the spring of 1988. At the time I had noticed that there existed almost no modern references covering the topic of U.S. Combat Helmets. Since I was enrolled in the School of Engineering and Computer Science at California State University, Northiridge, I decided to start my research there leveraging the assets of the university and employing the "scientific method" of discovery taught to engineering students. Between 1988 and 1990, I had gathered an extensive amount of information on the M-1 Helmet. What had been a simple quest for information, became the first and largest formal effort to compile the History of the M-1 Helmet. My early efforts in 1988 and 1989 led me to compile a small set of notes.

These early notes were compiled into a small booklet. The small booklet entitled "M1 Steel Combat Helmet; A Brief History and Visual Reference Report, 1941-1989", was the first effort that tried to document the history of the M-1 Helmet and make that information publicly available. Four revisions of this booklet were published between 1988 and 1990.

In the winter of 1990, I had amassed enough information to write a manuscript dealing with the history of the M-1 Helmet in World War II. Thus in January 1991, I wrote my manuscript on the history of the M-1 Helmet in World War II. Additionally, in the spring of 1992, I wrote a small manuscript on the M-1917 and M-1917A1 Helmets. Neither of these took the form of a booklet. By 1993, I had received numerous inquires from historians and collectors alike as to what happened to my efforts. So, in January 1994, I decided to manufacture a small number of copies on the M-1 Helmet manuscript as a booklet. This booklet was entitled "The M1 Helmet, 1941-1945; A Short History".

By 1995, Schiffer Publishing was kind enough to start publishing my work, and the  "The M-1 Helmet: A History of the M-1 Helmet in World War II" is the product of that effort.  In 1997, the book "U.S. Combat Helmets of the 20th Century: Mass Production" was published.

Substantiated research facts have always been my number one priority in the series of books I have written on the topic. Thus only primary source materials from the U.S. Military, the helmet contractors and engineering industry trade magazines of the period have been used in the writing of my books. Below is a listing of primary source concerns I have consulted, visited and interviewed in the writing of my several books on U.S. Combat Helmets:

In the process of researching U.S. Combat Helmets I have gathered a large collection of source material, enough to fill a two drawer file cabinet. I have combed over all this material, both textual and diagrammatic, to accurately document the information I write about in my many books.

I have spent a great deal of time and effort to research and provide the historian and collector with accurate information on America's combat helmets. For those of you who have bought any of my books in the past, I thank you and hope you have enjoyed my efforts. And for those of you thinking about purchasing a book, I am sure you will not be disappointed.
