Gertrude Protain MBE (8 July 1914 – 14 May 2005) was a Vincentian/Grenadian educator, politician, and tourism expert, as well as one of the influential feminists working in the Caribbean in her era.

[2] Blackman was educated in Kingstown, attending the St. Vincent Girls' High School and soon after her graduation, her family relocated to the nearby island of Grenada.

[3] Protain, along with other feminists including Grenadian Louise Rowley, Jamaican Una Marson, and Trinidadians Beatrice Greig and Audrey Jeffers led the spread of feminism throughout the Caribbean.

After two decades of service, Protain retired, only to return four years later to work for the Ministry of Tourism as the government's cruise administrator.

Protain organized tourism seminars for taxi drivers and street vendors so that they were able to provide high quality service and were knowledgeable about the island.
