Peter Joseph Osypowski, 71, passed away on Jan. 10, 2013, in Gloucester, Va.

He was born on Sept. 22, 1941, in Milwaukee, to Joseph and Esther (Wisniewski) Osypowski.

Peter grew up in Campbellsport, where he graduated from Campbellsport High School in 1959. After high school he joined the Army in 1960, where he served as a medical laboratory specialist until he retired in 1983. He worked as a consult for the World Health Organization, Pan-American Health Organization and for the Brazilian Ministry of Health while in the service. He received many medals and awards for good conduct, length of service, marksmanship, and many others.

Upon retirement from the Army he worked as a research technician and assistant graduate education director at the University of Wisconsin Medical School at the Sinai Samaritan Medical Center in Milwaukee, researching obstetrics and gynecology infectious diseases. He coauthored multiple articles in various medical journals and books, and was often invited to speak to medical students at Marquette University, testify in criminal cases and speak at conferences. Upon taking an early retirement he worked part time at Pick ’n Save until fully retiring in 2003. After retirement he spent many days enjoying his hobbies and babysitting his three granddaughters.

Peter’s hobbies included hunting and fishing. When he wasn’t doing those, he could be found playing cards at the West Bend VFW or the Senior Center.

Peter was preceded in death by his parents, Joseph and Esther (Wisniewski) Osypowski.

Peter is survived by his son Michael (Laurie) Osypowski of Yorktown, Va., grandchildren Ashley, Abigail and Amber Osypowski, brother Marty (Jane) Osypowski of Campbellsport, and two sisters, Kathy (Richard) Narwocki of Hartland and Joan (David) Lange of Milwaukee.
