Before Florence Nightingale we had Mary Seacole!! A woman who did more to advance the cause of nursing - and race relations - than almost any other individual.

Mary Seacole (1805–1881) was a pioneering Jamaican nurse, healer, and businesswoman whose contributions during the Crimean War have long been overlooked. After being rejected by British military and nursing authorities, she used her own resources to travel to the war zone, where she established the “British Hotel” near Balaclava.Image
The British Hotel was not a traditional hospital, but it provided food, supplies, shelter, and hands-on medical care to wounded and sick soldiers. Seacole was known for going directly onto the battlefield to tend to injured troops, earning deep respect and admiration from the men she cared for.
Florence Nightingale did not support Seacole’s work and declined to include her among her nurses. While Nightingale and some of her supporters viewed Seacole’s establishment critically—often dismissing it as overly commercial—there is no solid evidence that Nightingale directly called it a brothel. These tensions reflected racial, class, and ideological differences about who was considered “legitimate” within the emerging nursing profession.Image

Did you know Sesame Street was originally created for black and brown inner city kids?

A THREAD Image
Children usually spend a lot of time watching a lot tv and technically it was sort of a babysitter. It was even worse for inner city children whose parents spent endless hours at work, thus their kids were usually exposed to long hours of mindless programs.
Lloyd Morrisett, regarded as the father of Sesame Street and vice-president of the Carnegie Corporation with a Ph.D. in experimental psychology from Yale University developed
a special interest in children's education. Image

In 1963, 15 black girls were arrested for protesting segregation laws at the Martin theatre. Aged 12-15, they were locked in an old, abandoned stockade for 45 days without their parents knowledge. They came to be known as The Leesburg Stockade Girls,

A THREAD Image
The girls marched from Friendship Baptist Church to the Martin Theater, attempting to buy tickets at the front entrance, defying segregation laws. Police attacked with batons and arrested them, transporting them to a Civil War-era stockade in Leesburg, Georgia, 15 miles away. Image
The stockade had no beds, a broken toilet, and only hot water from a shower. The girls slept on concrete floors in sweltering heat, ate undercooked burgers, and drank from a single cup. Parents were not informed of their location for weeks, heightening their fear and isolation. Image

On this day in 1923, a lie by a white woman that she’d been sexually assaulted by a black man, led to the destruction of the predominantly African American town of Rosewood, Florida, thus the Rosewood Massacre.

A THREAD Image
Rosewood was a quiet, self-sufficient town in Florida. By 1900 the population in Rosewood had become predominantly African-American. Some people farmed or worked in local businesses, including a sawmill in nearby predominantly white town.
A rumour spread by a white woman, Fanny Taylor, sparked a massacre in the predominantly black town. Taylor claimed she was sexually assaulted in her house by a Black man. A group of white men believed her claims that she was raped by Jesse Hunter, a recently escaped convict.
