Mad scientist

A mad scientist is a scientist who is insane.

The term originated in literary works in the 19th century to depict the dangers of science.

In recent years it has been used whimsically by popular science writers to attract readers (things are more interesting if they are somehow dangerous).

Mad scientists are typically characterized by obsessive behaviour and the employment of extremely dangerous methods. The general rule to follow when you encounter mad scientist experiments is 'do not attempt this at home!'

characterizations:

• pursuit of science without regard to its ethical implications such as violating the Nuremberg Code;
• self experimentation;
• playing god;

example mad scientists:

• Dr. Jekyll (see Robert Louis Stevenson)
• Dr Frankenstein (in the film versions, at least)
• various parodies in Terry Prattchett, including Igor the manservant
• Dr. Josef Mengele
