 Friedrich August Kekule von Stradonitz

Coat-of-arms of August Kekulé von Stradonitz (1829-1896)
best known for his discovery of the structure of benzene (1865)

The above depiction of the coat-of-arms of Kekulé is due to Jochen Wilke.
The background is a conventional representation of the benzene molecule
(although actual benzene has hexagonal rather than triangular symmetry).

Gules, three angled fleams Argent pallwise [blades pointing counterclockwise]
between three trefoils Vert 
[pallwise inverted, in heart].
Crest:  A horse fleam Argent.   Mantling:  Gules and Argent.

In the above, the bracketed terms were introduced to lift
the ambiguities of the ancient German blazon which reads:

In Rot drei in Form eines Schächerkreuzes zusammengefügte, von drei
grünen Kleeblättern gewinkelte silberne Rossflieten oder Lasseisen. 
Auf der Helm mit rot-silbernen Decken eine silberne Rossfliete.

In 1865,  Kekulé  had a revelation of the  cyclic structure of benzene  in a daydream where he saw  snakes biting their own tails.  He first proposed a planar molecule of  trigonal  symmetry, with alternating single and double bonds  (instead of the currently accepted perfect hexagonal symmetry).
