Along with Sir Everton Weekes and the legendary Gary Sobers, he toured New Zealand with the West Indies team in 1955–56.
In 1965, Roberts teamed up with Robert Hill, Hugh O'Neale, Alvin Johnson, Franklyn Harvey, Anne Cools, and Rosie Douglas, among others, to organise the first of a series of conferences and events that would bring a host of distinguished Caribbean thinkers and writers to Montreal, including novelist George Lamming and C. L. R. James, one of the great thinkers of the last century.
These groups played a major role in highlighting social and political issues facing communities of African and Caribbean descent locally and internationally.
A voluminous reader who possessed a remarkably analytical mind, a vivid memory, and an insatiable appetite for learning, Roberts was also a teacher who served as an advisor and resource to many – including several prime ministers in the Caribbean.
The Alfie Roberts Institute expands upon his life work, and is home to a large collection of print and media materials primarily concerning Africa, the Caribbean, and their peoples.
