Prominent Armigerous Scientists and Inventors, in Chronological Order :
(see also:  contemporaries, others, celebrities, industrialists, explorers & shortlist)

WARNING : We are only presenting the heraldry  associated with  famous scientists and thinkers.  In a few cases, such armorial bearings are either family arms or  components  which appear in the arms of others  as if  the illustrious individual had borne them.  For James Clerk Maxwell or James Watt, the best evidence (yet) of an association with the arms featured here is the quartering of these arms by other family members...  Another example is "Sable a sun Or", which is an unambiguous heraldic reference to St. Thomas Aquinas in the arms of a number of institutions or individuals, although Thomas apparently never sported any arms himself. 

A  white background   indicates entries based on insufficient evidence.  The graphic renditions of some coats-of-arms (Gutenberg, Paracelsus, Bernoulli, etc.) are based on ambiguous blazons and may thus not be completely accurate...  This is very much a work in progress, and all your suggestions are welcome!

Remarks:

Our Fibonacci coat-of-arms is probably incorrect, since it is solely based on a modern description of the arms of a family bearing the Bonacci surname...  The arms given for Roger Bacon are those of another 13th century individual related to the famous nobleman-turned-friar.
 
For Saint Thomas Aquinas, the uncertainty is of a different nature since "Sable, a sun Or" is an unambiguous heraldic reference to the saint, especially within the arms of institutions named after him  [ 1 | 2 | Pell ].  However, there does not seem to be any direct evidence that Thomas himself used the symbol and/or the corresponding arms.  He was from the high nobility, but probably never bore the Aquino arms (the original arms were apparently "Or 3 bends Gules" and were later quartered with "per fess Gules and Argent, a lion rampant counterchanged").
 
Nicole Oresme probably bore the shield at left when he became bishop of Lisieux.  This was once also the shield of the city whose tinctures were changed so a chief of France could be added.
 
The ancient arms of the da Vinci family from Tuscany are well-known, and the fact that Leonardo was an illegitimate child may not have prevented him from using them in some way, although we have no evidence that he ever did.  The arms listed for René Descartes are those of his family and they are duly found in his own iconography; they are unrelated to his title of  Sieur du Perron  which Descartes kept the right to use for life even after selling in his youth the corresponding estate that he had inherited from his maternal grandmother  (his Mausoleum bears the Latin inscription  Renatus Descartes, Perronti dominus).
 
In Scotland, the right to bear arms is rigorously regulated:  The arms at left are the ancient arms of Lord Maxwell, chief of the Clan Maxwell  (there has been no recognized chiefs since 1863, and the last ones bore more complex arms).  The physicist James Clerk Maxwell would not have been allowed to bear the Maxwell shield without some mark of difference, although he was entitled to the Clan's badge and could wear the Maxwell tartan.  The arms shown at right are most probably the unregistered arms which the Maxwells of Middlebie bore before 1672  (when registration with the Lyon Office became compulsory).  The branch was revived by James' father, John Clerk Maxwell, who assumed the Maxwell name on inheriting Middlebie  (shortly after the birth of his only child).  [read more]
