Austrian artist Egon Schiele (1890-1918) is regarded as one of the most radical painters of the 20th century. Mentored by Gustav Klimt, the two artists shared a close friendship and influenced each other's work. Schiele's elongated, angular figures are unapologetically honest, characterised by bold continuous lines.
When drawing, the artist would keep unbroken eye contact with the life model, not taking his pencil off the page. He embellished his nude sketches with injections of bright colour, creating highly original works of art.
