Geoff Allen has been surrounded by forecasters all his life, though he generally did not realize it at the time. An early introduction to probability forecasting was provided by his mother, whose principles ("stay away from that cliff or you'll hurt yourself") were sometimes ignored and occasionally true.

He has been a member of the faculty of the University of Massachusetts since 1974. He received a bachelors degree from the University of Nottingham, and a Ph.D. in agricultural economics from the University of California, where he met Robert Fildes. Years later, while on sabbatical leave he visited Robert and was persuaded to take a vacation to Istanbul where there happened to be a forecasting conference (the second ISF). There he met Scott Armstrong. It would be nice to record that this marked the start of his forecasting career though he did not realize it at the time) and the rest, as they say, is history.

Nice, but not necessarily true. He spent many years working in the area of applied economics on a variety of topics: environmental policy, aquaculture production decisions and crop insurance, before realizing that most of these are in some way connected with forecasting.
