Franz Naegele

Franz Karl Naegele (7 December 1778 – 21 January 1851) was a German obstetrician born in Düsseldorf.

His son, Hermann Franz Naegele (1801–1851), was also a noted obstetrician.

He is remembered for "Naegele's rule", a standard method of calculating the due date for a pregnancy.

His name is also lent to "Naegele obliquity", also known as an anterior asynclitism.

[2] A variety of obliquely contracted bony pelvis where there is arrested development of one of the sacral alae, has also been named after him (Naegele's pelvis).
