A primary school teacher and member of the Boston Female Anti-Slavery Society, Paul also wrote the first biography of an African American published in the United States.

Known as the Juvenile Choir of Boston, Paul's African American students ranged from ages three to ten and sang patriotic and anti-slavery songs.

[3] Under Paul's guidance, "The choir's singing...meant that African American voices would quite literally be heard and would prevent the anti-slavery struggle from becoming an abstract enterprise whose goals were articulated only by white reformers.

[3] After the Boston Female Anti-Slavery Society (BFASS) was formed as an auxiliary of NEASS, Paul became one of the first African American members of the group.

James Jackson was one of Paul's students at Boston's Primary School Number 6 who died at just six years of age.
