This transformation from an exotic and expensive research tool into a basic source of information for the masses has occurred for several reasons. One is simply the relative proliferation of radars across the country. Another is in the ability to communicate the data from place to place. Still another is that the information provided by radar is simply so useful that it is foolish not to use it for many people. As the field of radar meteorology changed over the years, so, too, has the typical radar meteorologist. Based on photographs from some of the early radar conferences and actual observations of real, live radar meteorologists presenting papers at a number of radar conferences, I have watched the changes that have taken place over the years. Figure 1, first presented at the 22nd Conference on Radar Meteorology at Zurich, Switzerland (Rinehart, 1984), shows what the well-dressed radar meteorologist looked like over the years.
