Have you heard of Ada Coleman? Her patrons called her “Coley”. In 1903, she became the first female head bartender at the American Bar at the Savoy. Her skill mixing drinks and her strong personality first won the bar the renown it still enjoys today. When she retired, no less than 5 newspapers wrote articles about her impact on the London bar scene.
I was reading up on “Coley” when I came across a bio of her on a Mexican cocktail site that begins “Quizá sea extraño escuchar que una mujer haya desarrollado un papel fundamental en la historia de la coctelería” … translation: “Maybe it seems strange to hear that a woman has played a fundamental role in the history of cocktails”.
