Last month the Portuguese Province buried Fr Luis Archer, a brilliant geneticist who had been a Jesuit for 64 years. He taught molecular genetics in 13 different universities, being distinguished with the National Award 2004 in Bioethics. He also published 250 scientific articles about bioethics and molecular genetics. In the critically important area of bioethics, the scientific community respected Father Archer’s voice, especially during his Presidency of the Ethics National Council for Sciences of Life (1996-2001). A lover of music, literature and art, he lived easily with the dialogue between faith and science and with the mysteries he encountered in both.
