ICRC (International Cosmic Ray Conference)
The International Cosmic Ray Conference (ICRC) takes place every other year, in a different city around the world. Michael attended this conference many times, and collaborated on papers presented (by others) in numerous other years.
3rd ICRC Bagnères-de-Bigorre, France, 1953
The first one he attended was less than a year after arriving at Bristol, for the 3rd ICRC, held in July 1953 at Bagnères-de-Bigorre, at the base of the Pyrenees in France. This has subsequently become a famous conference, as multiple commentators have deemed it to be the birth of particle physics as a discipline, and the attendant changeover from cosmic ray particle research to earth-based particle accelerators.
In a talk at the Centenary of Cosmic Rays meeting at the University of Denver in 2012, Oliver Ravel said in conclusion:
The Bagnères de Bigorre conference (Fig 7), organized by Leprince-Ringuet and Blackett, was held in the small town located at the foot of the Pic. It is certainly one of the major conferences of modern physics for the richness of presented results. This congress is considered today as the starting point of the particles physics. The conference was concluded by Cecil Powell who said: "Gentlemen, we are now invaded, we are submerged, these are the accelerators". He has predicted in some way, the transformation of high energy particle physics research using the cosmic ray beam to research using more controlled beams of particles produced by man-made accelerators. Nevertheless, one century later, the vitality of cosmic ray research is always as in the pioneer’s time and the story continues...

11th ICRC in Budapest, Hungary, 1969
Another photo from the Hungary ICRC appears on the memorial site to Michael's Wash U physics colleague and friend, Professor Joe Klarmann.
Michael wrote an article for the Washingon University Magazine in the Winter 1970 issue called "Is This Trip Necessary?", an explanation and defense of scientific conferences (which discusses this 1969 ICRC from which he had recently returned).
36th ICRC in Madison, Wisconsin, 2019Michael did not attend this one, but in an interesting bit of symmtery, his grandson, Noah Friedlander did. Noah, an undergraduate physics/politcal science major at the University of Chicago at the time, was working in the lab of Dr. Stephan Meyer, working on a cosmic ray balloon experiment, UCIRC (University of Chicago Infrared Camera). Noah was a co-author on a paper presented at the conference, "UCIRC2: An Infrared Cloud Monitor for EUSO-SPB2."
This was only the fourth time that ICRC had ever been held in the United States (since its founding in 1947), and fortuitously was just a couple of hours drive north from Chicago (where Noah spent the summer working in the lab) !
