On Thursday July 11 2019, John Mcclelland from the United States left the following message for Gerhard Busse:
"Hi Gerd, I want to congratulate you on your well deserved award at ICPPP-20. I'm sorry that I didn't attend but it seemed like a long trip to a 78 year old. I am still active with my company but I mountain bike with an electric assist bike (Bosch). I wasn't able to find your current email address so I hope you get this message. Warm regards, John. Research Director. MTEC Photoacoustics, Inc. 1-515-292-#### (phone and fax)."
