A brief recollection of the history of the two-piece normal distribution discovery: 119 years from the first publication of Gustav Fechner original work until its latest re-discovery.
To find more about the two-piece normal including its definition, visualisation, random sample generation, and Python library see my next post.

If you are interested in reading more about the history I recommend:
- The Two-Piece Normal, Binormal, or Double Gaussian Distribution: Its Origin and Rediscoveries published in 2014 by Kenneth F. Wallis
[…] The two-piece normal was proposed by German physicist and phycologist Gustav Fechner -who is also consider the founder of psychophysics– around 1887 but published posthumously ten years later. Unfortunately, Fechner work did not become popular and this lead to a series of re discoveries (as recent as 2016!). You can see a brief recap of this interesting journey in my previous post Brief History of the Two-Piece Normal. […]
