A lateral thinker long before the term was coined, Harry Warren applied his intellectual curiosity and scientific mind to the field of geochemistry, where he made remarkable contributions to prospecting and mineral exploration. He was a pioneer in a discipline which came into its own, to a large extent, through his efforts.

When the modern age for exploration geophysics began more than four decades ago, Norman Paterson was one of its leaders. Today, he is known worldwide for his innovations in geophysical technology and skilled practice of geophysical techniques and interpretation.
