Fr. Emil Neubert was, arguably, the most extraordinary Marian writer of the twentieth century. St. Maximilian Kolbe was so impressed with one of his books that he struck up a friendship with him. Many people, however, have not heard of him. Here is a good article about him. Fortunately, Fr. Neubert also wrote an autobiography, which you can get here! I have dedicated a Pinterest board to him where you can also get some of his previously untranslated works. I have three more of his works in preparation. He used to write about the Blessed Virgin for three hours a day, and he wrote books for every state of life. His autobiography is very inspiring. It is to be hoped that he will be canonized.
