When considering how to summarize the changes in gravity and magnetics during the last 25 years, I felt I needed a theme to bind the discussion together. I also wanted to include input from my gravity and magnetics (G&M) colleagues. I decided to use my career as the vehicle for my initial, rather philosophical, discussion of changes that I have seen in the business end of G&M. I end with a list of important technical advances since 1980. I want to offer my thanks to the dozens of G&M experts, professors, gurus, and friends that gave me input; many of the most arresting quotes have been inserted verbatim in the text at points where I felt they were particularly on target. I also recommend that you read the 75th Anniversary technical summary with articles in the November/December 2005 issue of Geophysics.
