Hermann Seger (1832–1893) was a German ceramicist who is widely credited with pioneering the development of the pyrometric cone, which enabled the rapid growth of the ceramic industry around the turn of the century.

He became editor of a ceramic trade journal in 1872 and used his new position to draw attention to various advances being made abroad, such as the continuous kiln and new machinery.

[2][1](p xvii) He worked with Georg Wilhelm Timm to develop new methods of applying glazes and engobes to whiteware ceramics.

[3][1](p xx) In 1890 Seger left the KPM due to declining health and spent the remainder of his life focused on editing his trade journal Thonindustrie-Zeitung.

[1] The American Ceramic Society's first action after approving their constitution was to translate the complete works of Seger, since he was considered the world's pioneering ceramicist.
