      Dear All<br>
      <br>
      Let me share with you - in his memory - this picture of a young
      Ken Downing that I took when we first met in March 1977 at the
      EMBO course in Basel, organized by Ueli Aebi and the late Ross
      Smith. The second picture is Ken in vivid discussion with Ueli
      Aebi over a slide on the overhead projector. <br>
      If I remember correctly we discussed, at that meeting, the
      transfer properties of a microscope system equipped with a
      half-aperture.<br>
      <br>
      Rest in peace Ken,<br>
      <br>
