Anyone who saw All Creatures Great and Small almost had to love it, and anyone who loved it had to think the best character was played by Robert Hardy. Siegfried Farnon was a fictional version of a real person created by James Herriott, pen name of a real life veterinarian who wrote fiction based on himself and his friends.
Siegfried was not the main character, but he was the dominant one. Employer of James and big brother of Tristan, his dominant, boisterous, hotheaded and contradictory personality was basically just hilarious and endearing. Veteran actor Robert Hardy brought him to life and made Siegfried unforgettable, a performance that no one could have improved on. Rest in peace, Mr. Hardy, and thank you for Siegfried.
