1865 – Hofmann's Croquet Ball Models

August Wilhelm Hofmann was the first to introduce physical representations of molecules into lectures during his Friday Evening Discourses presentation "On the Combining Power of Atoms" at London's Royal Institution of Great Britain in . He introduced a colored set of four croquet balls to represent atoms (hydrogen, oxygen, chlorine and nitrogen), implanted with a fixed number of sticks corresponding to each atom's valence. Thus we distinguish the chlorine atom as univalent, the atom of […]

1866 – Dewar's Brass Strip Models

Mechanical arrangement adapted to illustrate structure in the non-saturated hydrocarbons by the chemistJames Dewar. The model is made of bars, clamped together so as to allow free motion. In order to make the combination look like an atom, a thin round disc of blackened brass can be placed under the central nut. At the ends of the arms are holes to connect one carbon atom with another by means of a nut. The structure at the bottom right of his figure is now called "Dewar benzene". I bring […]

2004 – Scripps' Molecule Models

Since 2004 the Molecular Graphics Laboratory at the Scripps Research Institute has been making heavy use of 3D-printed full-color physical molecule models, some of which are articulated (left image), flexible (middle image), and even self-assembling (right image, see video). They also publish augmented reality systems that use those physical models. Also see our entry 1995 – SDSC TeleManufacturing Facility.

2005 – Molecular Jewellery

Raven Hanna got her PhD in biochemistry in 2000, and five years later, she became an artist and started to create jewelry based on molecular structures in order to communicate science through art.
