Woman of the Century — Annie Fillmore Sheardown (1893)
“ She studied with other teachers, and in 1891 she made a most valuable discovery relative to the voice, finding the voice to be an exact science, a principle to be demonstrated, with laws as unalterable as those of mathematics. She is the first person to note this great fact. She has always felt there was something wrong in all methods, and now, looking at the voice as a principle, she is able to demonstrate where the error lies. ”
