His observations were some five times more accurate than the best available observations at the time. An heir to several of Denmark's principal noble families, he received

Given the limitations of the naked eye for making accurate observations, he devoted many of his efforts to improving the accuracy of the existing types of instrument — the sextant and the quadrant. He designed larger versions of these instruments, which allowed him
