Answer:
Anne's diary survived through Miep Gies, she was one of the people that helped everyone hidden in the secret annex, and kept Anne's writings safe in a drawer. Not only the diary, but also the revisions. Miep gave the diary to Otto, (Annes father) Otto was fascinated with all of Anne's writings so he had the diary typed up, and looked for a publisher. Eventually one of Ottos friends showed the diary to a historian, who ended up writing a front page article on it. This gained much attention, and thus, Anne Franks diary was soon published!
