Johan August Brinell was a Swedish metallurgical engineer. Brinell is noted as the creator of a method for quantifying the surface hardness of materials, now known as the Brinell hardness test. His name is also commemorated in the description of a failure mechanism of material surfaces known as Brinelling.

According to Ulla, 200 examples of this medal were struck in silver.
