I was recently given a copy of the remarks made Lester B. Pearon's late son Geoffrey (he's GAHP in the top right corner) on the unveiling of his fathers statue on Parliament Hill in 1990. Geoffrey Pearson wrote"Seize the Day : Lester B. Pearson and crisis diplomacy" (Carleton University Press, 1993) which traces his father's role as Secretary of State for External Affairs and was working through a book on LBP as prime minister before he passed away in 2008. I do believe (though I'd have to check to confirm) that he assisted in LBP's memoirs and a biography written on the former Prime Minister. Geoffrey Pearson led a distinguished diplomatic and public service career,with several ambassadorial positions, including to the USSR from 1980-1983.
Anyway, here's a photograph of the remarks. I thought they were worth sharing.
