Born in a country town in Australia, Jay Caselberg travelled far and wide while growing up. His first overseas trip was to Istanbul in 1969, where he lived for two years, and later to Cambridge for a year. His family also travelled around the world during these trips.

Originally opting for a BSc degree in Biochemistry, he changed to a BSc degree in Psychology and transferred to the University of Wollongong from Sydney to get a BA Psych. From there, he took on History and Philosophy of science and eventually got an honours degree in the topic. Pursuing his Doctorate through means of a Commonwealth Scholarship, he moved to the University of New South Wales in Sydney. A while before he was due to submit his dissertation, he realised that academia wasn't going to fulfil his ambitions and he started working. After joining several IT companies, he found one that he stayed with, and transferred to work in London several months later.

From that time on, he travelled extensively, spending time with clients throughout Western, Central and Eastern Europe and Africa. Towards the end of that time, already a champion historical wargamer, he retired from competition and decided to focus on his love of writing. In 1996, he started writing with a passion. For nearly the next two years, he wrote full time and garnered his first few publications writing as James A. Hartley. In 1998, he rejoined the workforce.

His next job involved even more travel, having initial responsibility for 54 countries, dealing with internal management systems for a major accounting firm. This role eventually grew to encompass a number of different global projects. During the constant travel, he wrote, and continued to write. In mid 2002, he became freelance and worked for a number of major firms worldwide.

Since then, he has continued to write and publish, both as Jay Caselberg and James A. Hartley.
