Henry Jackson van Dyke (1852 - 1933) was an American author, educator, and clergyman.He graduated from Princeton University in 1873 and from Princeton Theological Seminary, 1877. He served as a professor of English literature at Princeton between 1899 and 1923.Van Dyke chaired the committee that wrote the first Presbyterian printed liturgy, The Book of Common Worship of 1906. In 1908-09 Dr. van Dyke was a lecturer at the University of Paris.By appointment of President Wilson, a friend and former classmate of van Dyke, he became Minister to the Netherlands and Luxembourg in 1913. Shortly after his appointment, World War I threw Europe into dismay. Americans all around Europe rushed to Holland as a place of refuge. Although inexperienced as an ambassador, van Dyke conducted himself with the skill of a trained diplomat, maintaining the rights of Americans in Europe and organizing work for their relief. Upon his resignation as ambassador, he returned to the United States. He was elected to the American Academy of Arts and Letters and received many other honors.Van Dyke was a friend of Helen Keller's. Keller writes, "Dr. van Dyke is the kind of a friend to have when one is up against a difficult problem. He will take trouble, days and nights of trouble, if it is for somebody else or for some cause he is interested in. 'I'm not an optimist,' says Dr. van Dyke, 'there's too much evil in the world and in me. Nor am I a pessimist; there is too much good in the world and in God. So I am just a meliorist, believing that He wills to make the world better, and trying to do my bit to help and wishing that it were more.'"
