Why did Claude Bernard’s apprenticeship with a Lyon apothecary end?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

Claude Bernard’s apprenticeship with a Lyon apothecary ended because his employer was displeased with his focus on writing plays rather than his work duties. During his time as an apprentice, Bernard spent his limited free time writing a historical drama titled Arthur de Bretagne, which distracted him from his menial tasks at the pharmacy. Consequently, the apprenticeship was halted, and he returned home in July 1833.1
