Dame Albertha Magdelina Isaacs DBE (née Hanna; 18 April 1900 – 1 August 1997) was a Bahamian teacher, tennis player, women's rights activist and politician.

Because women's roles were limited to fundraising, she turned her attention to the suffrage movement and focused on gaining the right to vote.

[1] Socio-economic barriers to women created disadvantages in education, employment, family support, inheritance and political activism.

The Dame Bertha Isaacs trophy is awarded at the Commonwealth Caribbean Lawn Tennis Championship to the female player who has demonstrated the highest standard of court behavior, quality of play and sportsmanship.

[13] Her great-grandson is former Bahamian Major League Baseball player and current New York Mets First Base Coach Antoan Richardson.

In his previous coaching stop with the San Francisco Giants he wore the number 00, representing her birth year to honor her legacy.
