Andrew Gibb Maitland (1864 – 1951) was an acknowledged authority on underground water and had early successes in the West locating bores between Geraldton and the North West Cape. He worked in the Kimberley Division with F S Drake Brockman in 1901 and in 1903, spent several long and arduous seasons in the Pilbara region mapping a vast area. Water and gold were crucial to the posterity of the West at this time, and Maitland and his staff devoted much attention to the Pilbara goldfields. Little did they know what great wealth would be found sixty years later.
William Dugald Campbell (1880-1952) was an English Geologist working In Australia and New Zealand and undertook pioneering ethnographic work in the Eastern Goldfields, the North West and the Murchison. Working as Assistant Geologist to Gibb Maitland he also contributed to many geological surveys at the time.
