A German emigrant to America who claimed to be a doctor without ever finishing the degree, and who solved the two blockers of premature-baby care (cost and practice volume) by turning it into a sideshow: free care for the babies, paid tickets for the public. Air filters, stable temperature, strict hygiene, no smoking wet nurses. He saved more than 6000 of the 8000 babies that went through his incubator shows, an 85% survival rate for children who otherwise all died. The full story: El zoo de bebés prematuros.
