[3] The following year he published The Geometry of Harmonic Functions, which won the Carl B. Allendoerfer Award for 1995.
[4][5] Needham wrote the book Visual Complex Analysis, which has received positive reviews.
"[7] In fact Douglas Hofstadter wrote "Needham's work of art with its hundreds and hundreds of beautiful figures á la Latta, brings complex analysis alive in an unprecedented manner".
In 2001 a German language version, translated by Norbert Herrmann and Ina Paschen, was published by R. Oldenbourg Verlag, Munich.
In 2021, Needham published Visual Differential Geometry and Forms: A Mathematical Drama in Five Acts (Princeton University Press)[9].
