Sheldon Wald and I were graduate students in physics at Arizona State University in the 1960s. On March 16, 2013, Sheldon Wald wrote me, " I came to ASU in August of 1969. I was in the mild-mannered studious group .... These were probably the best years, and I have very fond memories." -- Jane Jackson, Dept. of Physics, Arizona State University (June 2020. I learned about Sheldon's death only last month.)
