Johann Davis Michaelis (1717-19) was a theologian and orientalist, whose fame today rests upon the fact that he was responsible for the first scientific expedition to Arabia Felix, namely that of Niebuhr. 
In 1753, he had come up with the idea for the the Royal Danish Arabia Expedition (1761-1767) and had gotten the Danish minister Bernstoff to agree to it. In 1760, when the expedition was becoming a reality, Michaelis recommended Niebuhr as a participant, and he outlined the entire purpose of the trip - namaly the list of 100 questions that he prepared and published for the members of the expedition, in order for them to answer in the course of the voyage. For all intents and purposes, Michaelis was the spiritual father of the Arabia-expedition. 

As a theologian and an orientalist, many of Michaelis' questions have root in the Bible. But unlike many other theolgians of the time, Michaelis sought to shed light over biblical themes through sources outside of the Bible - especially from the Middle East, not least Arabia. In this regard, his 100 Questions also came to be a precursor to the emergence of modern bible science.
