(Portland, OR)  --  Family and friends are paying tribute to a 92-year-old Holocaust survivor who lived through five forced labor and concentration camps in Nazi-era Germany.  The family of Alter Wiener gathered yesterday to commemorate the 30-day period following burial, called shloshim in the Jewish faith.  Wiener died last month after being hit by a car while crossing the street in Hillsboro.  KATU reports Wiener was one of only a few remaining Holocaust survivors living in the Portland area.  He documented his life and trials in a memoir titled "From a Name to a Number: A Holocaust Survivor's Autobiography."
