Heider was the son of the lodge weaver Georg Schmidt called Haider († 1588), 1569 to 1588 mayor of Nördlingen, and Ursula Isenmann († 1581), the niece of Johann Isenmann (around 1495–1574), the first Protestant abbot of Anhausen Abbey the Brenz . Since his parents died early, he was raised by his half-brother, Superintendent Wilhelm Friedrich Lutz (1551–1597), and by his brother-in-law, the Oettingian Chancellor Jakob Moser, who sent him to the high school in Ulm .
After receiving his doctorate in 1598 at the University of Jena as Dr. jur. Heider joined the imperial city of Lindau as a syndic in 1601 . In the following year he married Elisabeth, a daughter of the mayor of Lindau , Valentin Funk von Senftenau (also war paymaster in Hungary and Reichspfennigmeister adjunct). With her he had six sons and 5 daughters, some of whom stood out in history: Valentin Heider as lawyer and envoy Lindau at the Treaty of Westphalia , Jakob Heider as lawyer and syndic in Lindau and Daniel Heider as mayor of Lindau.
Through the marriage of Elisabeth Funk von Senftenau, Daniel Heider got access to the leading circles of the city, was accepted into the Lindau patrician society Zum Sünzen and became co-owner and heir of Senftenau Castle .
After his father Georg had already received a letter of arms from Imperial Vice Chancellor Johann Ulrich Zasius zu Augsburg in 1566 , Daniel Heider received from Emperor Ferdinand III in 1641 to Regensburg , together with his sons Valentin and Jacob . a letter of nobility .
With the Thorough Execution of 1643, a major monumental work appeared, a very extensive rejection of the claims of the Lindau women's monastery, which was involved in constant disputes with the Protestant city, to the urban territory. Heider proved the alleged diploma of Emperor Ludwig II from 866 to be a forgery - an early, still imperfect example of the diplomatic method. The very awkwardly written book is still of value for the Lindau city historiography due to the large number of sources with document prints.
