Dr. Jona was the longest serving president in the Club’s history. During the lean times of the Depression years in the 1930s, he guaranteed player payments from his own pocket and also kept the Club alive with similar generosity. He would treat all the injured players at his home after the game on a Saturday night at no expense.
In a visionary move to promote football and to encourage local recruits, he introduced the under 15’s school boy competition to play curtain raiser matches at Glenferrie in 1935. This was the forerunner to the Hawthorn Rovers, which started the following year. Many future Hawks would graduate from these teams. Such was his vision.
