# bio (long form, separated for readability)
bio: |
  Roger Charles Louis Guillemin was born in France on January 11, 1924, and built his career as a neuroscientist across two continents. His research focused on neurohormones, the chemical messengers that let the brain control the endocrine system — a connection many doubted existed. The work was painstaking: isolating infinitesimal quantities of these substances from enormous amounts of animal tissue. In 1976 he received the National Medal of Science, and the following year the Nobel Prize for Medicine, shared with Andrew Schally and Rosalyn Sussman Yalow. He died on February 21, 2024, a century after he was born.
