Missed your Grandmother by 4 months. My Mother, brother and, myself emigrated to Canada in July of 1954 on the Arosa Kulm to be re-united with my Father. I was just 5 but it was an exciting time and the memories are vivid. The experience may have contributed to my eventual career as an officer in the US Merchant Marine.
I recall our room mate was the grand daughter of Rudolph Diesel, the inventor of the diesel engine. She and her husband came to visit us years later in Canada. She shared with us her suspicion that Rudolph was murdered at sea over an issue involving his patent for the diesel engine.
