Alexander Herbert Imich (February 4, 1903 – June 8, 2014) was a Polish-American chemist, parapsychologist, zoologist and writer who was the president of the Anomalous Phenomena Research Center in New York City. He was born in 1903 in Częstochowa, Poland (then part of the Russian Empire) to a Jewish family.
Imich, a supercentenarian, also became the oldest living man at age 111 after the death of almost 112-year-old Arturo Licata, of Italy, on April 24, 2014. Until his own death a little more than a month later, aged 111 years and 124 days, Imich was certified by Guinness World Records as the world's oldest living man.
Imich was also the last surviving veteran of the Polish-Soviet War.

Edmund Faustyn Biernacki (19 December 1866 in Opoczno – 29 December 1911 in Lwów) was a Polish physician.Biernacki was the first one to note a relationship between the sedimentation rate of red blood cells in a human blood sample and the general condition of the organism. This method, known as the Biernacki Reaction, is used worldwide to assess erythrocyte sedimentation rate (ESR), which is one of the major blood tests.
