 Lindsay was able to secure a three-year apprenticeship in dentistry through a family friend, but did not feel this was enough and sought to enrol in dental school.She passed preliminary examinations, and in 1892 she applied for entry to the National Dental Hospital in Great Portland Street.The dean, Henry Weiss, refused to admit her because she was a woman; he was so concerned that she would distract the male students that he interviewed her on the pavement outside the school.
