Beatrix did not receive formal art lessons until the age of 12, when she was taught for five years by a Miss Cameron and sat examinations at the art schools attached to the South Kensington Museum (later renamed the V&A). Shortly after this, at 17, she had private lessons in oil painting with a professional artist called 'Mrs A'. By this time already quite accomplished as an artist, she also began to draw what she observed through microscopes with an eye of an investigative scientist.
Into her twenties Beatrix developed a meticulous watercolour dry brush technique and this coincided with her growing interest in fairy tales and inventing imaginary images featuring anthropomorphic animals. Adept at pen and ink line drawing, she would also write illustrated letters to children describing amusing or interesting anecdotes about her holidays, which would later morph into her hugely successful storybook career. The urge to sketch never left Beatrix and she continued to draw animals and landscapes even as she was heavily engaged in farming later in her life.
