Remembering Professor R. Darrell Bock

It is with great sadness that we acknowledge the passing of R. Darrell Bock. Among his many incredible contributions to science and psychometrics, Professor Bock was also co-founder and long-time President of SSI. The company would never have existed without Professor Bock and the history of scientific software would have been drastically different without his contributions. The staff at SSI express their heartfelt condolences to Professor Bock’s family and friends. For more information on his amazing life and contributions, you can find his obituary (penned by Robert Gibbons and Tania Bock) here.
