<p class="MsoNormal"><font size="3" color="black" face="Calibri"><span style="font-size:12.0pt;color:black">I was very sad to hear of the passing of Angel Vassilev. I first got to know Angel through his collaboration with my PhD supervisors, Margarita Zlatkova
(Vidinova) and Roger Anderson at the University of Ulster, and subsequently I had the privilege of collaborating with him on some projects in spatial summation in the S-cone pathway. His knowledge and love for psychophysics were a huge inspiration to me in
my early career and his published works shaped my own primary research interests. In addition to his contributions to basic psychophysics, mentioned by others, Angel’s research is also highly applicable to clinical psychophysics, including perimetry.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font size="3" color="black" face="Calibri"><span style="font-size:12.0pt;color:black">Angel was not only a great scientist, but also a really lovely man. He was kind and generous, and always extremely helpful and insightful in discussions
of experimental design and physiology. He was particularly eager to enthuse and help develop the careers of novice researchers. Psychophysics has lost a great man. Angel will be dearly missed.<o:p></o:p></span></font></p>

professor Angel Vassilev has passed away. Professor Vassilev was a prominent Bulgarian scientist in the field of vision. After obtaining a PhD at the Institute of Physiology “I.P. Pavlov” while working with professor V. D. Glezer, he was actively involved
in the study of several key issues in the field of visual psychophysics and electrophysiology. He had a long and successful career as a Professor of Visual Physiology at the Institute of Physiology in Bulgaria where he founded his laboratory “Visual Information
Processing” in 1978. He led a wide range of original research studying the latency of visual perception as well the latency of individual waves of visual evoked potentials at different spatial frequency, perception of orientation, flicker perimetry, the short
wavelength cone pathway etc. In 1987, he organized the Tenth European Conference of Visual Perception in Varna, Bulgaria, giving the unique opportunity to young scientists to meet world-renowned scientists visiting Bulgaria for the first time. </span><o:p></o:p></font></p>
