A new song is born today, in celebration of the 111th birthday of humanitarian Dr. Lotta Hitschmanova C.C. (1909-1990), who was recently nominated to appear on the new Canadian $5 banknote.

Thanks to her heart-felt TV and radio PSAs in the 1950s through to the 1970s, Lotta single-handedly made 56 Sparks Street in Ottawa the most famous address in Canada.

Happy birthday Lotta!
