Providencia Paredes, the special assistant to former first lady Jaqueline Kennedy Onassis, has died.

Paredes' son, Gustavo Paredes, announced her death on his Facebook page. Paredes died in Washington on March 18 at the age of 90.

In his post, Gustavo Paredes wrote that his mother was born in the Dominican Republic and was the first person of Latino descent to work in the White House as part of president's inner circle.

In addition to helping the first lady keep track of engagements, field phone calls and interface with fashion designers, Paredes also helped Onassis practice her Spanish in advance of speeches in Latin American countries and before Hispanic communities.

Paredes described his mother as "a woman of immense will, passion, curiosity and a zest for life."
