Jacqueline Amezcua Trouillot (1929, Port-au-Prince, Haiti) is a Haitian-American self-taught painter who began painting at the age of 90, after a lifetime dedicated to medicine, family, and intellectual life. In 1958, freshly graduated as the only woman pediatrician of her generation at the University of Pennsylvania, she moved to Mexico City to join a team of six physicians whose research contributed to the understanding and treatment of rheumatic fever worldwide. Diagnosed with mixed dementia in 2018, she turned to painting during the early months of the COVID-19 pandemic in May 2020, when art emerged as an unexpected form of expression that helped her navigate the illness. Working instinctively in a process closely related to action painting, with the canvas laid flat and rotated in all directions, she developed a powerful abstract language rooted in gesture, movement, and color. To date, she has produced over 500 paintings and maintains a daily practice from her home in Coyoacán, Mexico City.
