My colleague Chie Okamoto-san informed it to me.
It is very very sad news for me.
Although last time I met Bill-san was more than 10 years ago, I still remember him and good days for collaboration work with him.
Actually, since I started to work at Sumitomo Heavy Industries, Ltd. (SHI) in 1991, my job history is always with our 4K-GM cryocooler although my role changed several times, such as R&D engineer, Sales Staff, Management of subsidiary in Germany (SCEG), and QA senior engineer.
It definitely means that my history in SHI is always with Janis.
I also met Bill-san several times, and always appreciate his warm and collaborative work with us.
Especially, when I was working in SCEG (Between 2004 and 2008), Bill-san came to Germany every year to support Cryophysics GmbH (They are also SHI’s sales representative) at German Physics Show.
We always work together while operating Janis’ cryostat with Sumitomo cryocooler.
It was always very exciting, and impressive time for us.
Let me attach two photos with Bill-san. It was taken in 2006 in Dresden, Germany.
If you will have the opportunity to contact with Bill-san’s family, please let them know my deep appreciation that I could work with Bill-san very closely.
