It is my very sad responsibility to advise the HHS Alumni Association that Leo passed away on January 21, 2013. He was not ill very long - pancreatic cancer was discovered just after the New Year (the tumor on December 18) and it rapidly went to his liver. He was on continual pain medicine and hospice care for about 1 week and died peacefully.
He loved being a HHS Alum. He was born in Dailen China on December 2, 1940 and died in Monrovia CA.
