 After the Armistice, students, predominantly American, flocked to Renié and spread her teaching to conservatories over the world.Severe sciatica and neuritis, as well as bouts of bronchitis, pneumonia, and digestive infections in winter, nearly disabled Renié, but she continued giving lessons and concerts despite the intense level of sedatives she was taking.When Tournier retired from the Conservatoire after 35 years, Renié was offered the job, but declined, (amusedly) saying she was four years older than Tournier.
