Suggestions/plans to edit

I may decide to develop this page in the coming weeks as part of a college project. I would hope to expand his biography, his work with Earth’s magnetic field, and his manufacturing. Here is some early information that could be included. After settling in Nuremberg, Hartmann became the vicar of the church of St. Sebald and served in that position until 1544. The scientific tools Hartmann constructed were often made of expensive materials such as brass, ivory, and gold. Hartmann was also an early printer astrolabes made of paper. Hartmann was a friend of Nicolas Copernicus’s brother, Andreas Copernicus, and was an early supporter of Copernican cosmology. References: Lamprey, J. P. (1997).

External links modified (January 2018)

Hello fellow Wikipedians,

Added archive https://web.archive.org/web/20050909033634/http://www.liv.ac.uk/~jonkers/physikjournal.pdf to http://www.liv.ac.uk/~jonkers/physikjournal.pdf

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

Suggestion

I would like to know more about the middle of his life. --Weston Robertson (talk) 16:51, 21 February 2020 (UTC)[reply]

proposed changes to be made

I am going to add information about Hartmann's work for the church and create a citation after the sentence stating when he settled in Nuremberg. Also information about his use of refractive sundials. Weston Robertson (talk) 16:16, 6 March 2020 (UTC)[reply]

Hartmann's 1537 batch of astrolabes for the 39° latitude plate were found to be inaccurate, having the almucantars spaced out too far. Of the four astrolabes in that production run, all of them had these errors. This led to the conclusion that it was a simple human error, and shown a light on the amount of work that went into each of these instruments. Following the discovery of these errors, a deeper look went into Georg's manufacturing methods.Ianq5d (talk) 16:53, 6 March 2020 (UTC)[reply]

Changes

I am going to add more information about the different kinds of instruments that Hartmann manufactured as a well as a new section detailing where some of Hartmann's instruments are on display in museums across the world. Weston Robertson (talk) 13:46, 10 April 2020 (UTC)[reply]
