Until the Houston Convention in 1914, Rotary had celebrated all conventions in August. After the convention in Buffalo, 18-21 August 1913, the dates of the Houston Convention were changed to 22-26 June, 1914.
At this point, Rotary established a tradition, programming the convention for a date near the end of the Rotary year, in May or June.
Although the present practice to identify the salient president of Rotary International with the convention that is celebrated at the end of his or her year of office, does not necessarily apply to the conventions celebrated during the term of office of Frank L. Mulholland, 1914-15.
Trivia: The smallest convention was the first, 1910, with 60 attendees.
