The Treasury Department announced Wednesday that abolitionist Harriet Tubman will replace former President Andrew Jackson on the new $20 bill while Alexander Hamilton will remain on the front of the $10 note.

Treasury Secretary Jack Lew formally announced an array of design changes to Americas currency, largely geared toward honoring the contribution of women in the countrys history.

Our currency will now tell more of our story, Lew said.

In being featured on the front of the $20 bill, Tubman will be the first African American on U.S. paper money ever, and the first woman in 100 years. 

Lew called it a powerful message, and described Tubmans life as the essential story of American democracy. Jackson, the nation’s seventh president and a slave owner, will be pushed to the back of the bill.

Lew said the back of the $5 bill also will be changed to reflect historical events at the Lincoln Memorial including Martin Luther Kings I Have a Dream speech and black female singer Marian Andersons famous 1939 performance. The back of the $10 note, he said, will honor heroes of the campaign for womens right to vote.

But on the front of that bill will remain Hamilton, whom Lew described as the architect of our economic system.

Lew is hoping to unveil the new bills in 2020.
