The author was born Keith James McDonald in June 1941 in Melbourne, the capital city of the Australian State of Victoria. He grew up on farms and attended boarding schools, then Sydney University, graduating in 1962 with a double major in Mathematics and Physics. In his teens he acquired the name “Tim”, hence “K.J. Timothy McDonald.”
After university he taught in three different Catholic high schools for the following 17 years, the last eight as deputy headmaster for two years and then, for six years, headmaster, that boys' only school becoming a coeducational institution with an enrolment of over 1600 students on four campuses.
For over thirty years, K. J. Tim McDonald has walked the quiet halls of classroom education and historical research. His work does not separate the geometry of the cosmos from the narrative of the soul.
Through carefully documented biographies and rigorous mathematical guides, he offers readers a map to explore complex truths with intellectual dignity and scholarly warmth.
