Remembering Leo
  Leo Breiman was a unique character. There will not be another like him. I consider it one of my great fortunes in life to have know and worked with him. Along with John Tukey, Leo had the greatest influence on shaping my approach to statistical problems. I did some of my best work collaborating with Leo, but more importantly, we both had great fun doing it. I look back on those years when we worked closely together with great fondness and regard them as among the happiest and most fruitful of my professional career.
