H. KAMERLINGH ONNES—FREETH 535 
member of practically every learned society in the world. Onnes 
was awarded the Rumford medal of the Royal Society in 1912 and 
was elected a foreign member of the society in 1916. 
Turning to his personal side, it is impossible to speak of him with- 
out emotion. Onnes was one of the most genial, kind-hearted, and 
accessible men who ever lived. He made unremitting efforts toward 
the feeding of children in the destitute areas of Europe in the years 
immediately following the war. To young men, he was an inspira- 
tion. The writer will always remember, with gratitude, his ex- 
traordinary kindness and hospitality. He practically kept “ open 
house.” 
Onnes’ scientific memory is imperishable, and his personality 
will never be forgotten by any one who had the privilege of knew- 
ing him.
