Rajinder Singh Tumber (R. S. Tumber) was born in April 1983 at the British Hospital for Mothers and Babies in Woolwich, and raised in Kent, England.

Tumber is a cyber security specialist, sci-fi novelist, multi-genre author, cryptocurrency investor, and an inventor.

Selected as a FINALIST for the "Personality of the Year" award in the cyber security industry, Tumber has been working within the private and public sectors; most recently in aerospace and defence. With over a decade of experience in the domain of cyber security, his work in thought-leadership has been published in national and global magazines and newspapers.

In 2007, Tumber obtained an MSc Information Security from Royal Holloway, University of London. Prior to this achievement, Tumber studied at the University of Westminster, to obtain a BSc Computer Science (Hons).

However, Tumber yearned for greater knowledge - not just within the scope of Cyber.

For years, he has been fascinated with philosophy, astronomy, ancient history and other subjects beyond the public eye. Years of research and questioning of mainstream concepts have led him to write a range of eye-opening books, to inspire and enlighten those who are seeking a life of fulfilment; those who are not content with their current lives.
