Jay Caselberg was born in a country town in Australia and then traveled extensively while growing up. His first expedition was to Istanbul in 1969, where he lived for two years, and then later, in 1973 to Cambridge for a year. During both these trips, the family traveled thoughout the world.
Starting a BSc in Biochemistry in Sydney, he changed to a BSc Psych, then transferred to the University of Wollongong to do a BA Psych. There he discovered History and Philosophy of Science, which was to become his major and eventually, his Honours Degree. Taking up a Commonwealth Scholarship to pursue his Doctorate, he transferred to the University of New South Wales in Sydney, claiming from the start, that his degree was simply practice to write large, cogent volumes of material. A short time before handing in his dissertation, he realised that academia wasn't going to fulfil his ambitions and he stepped out into the workforce, joining a couple of IT companies in succession, until he found one that stuck. Nine months later, he transferred for work to London.
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, the global firm for which he worked ceased to exist.
Since then, he has continued to write and publish, both as Jay Caselberg and James A. Hartley.
