The most prolific Loch Ness monster eyewitness is Alex Campbell, who worked as water bailiff at the loch for over 40 years until the 1980s. During that period he claimed no fewer than 17 separate observations of Nessie, beginning in May 1934 when he saw something with a "swan-like" neck and a total length of around 9 m in the water.
