In holomorphic dynamics, there are examples of rational maps on the Riemann sphere having only repelling cycles (i.e., whose Fatou set is empty) , and a class of such examples is associated with elliptic functions. This class is called "Latt\'es examples", because in 1918 Samuel Latt`es constructed an $f$ satisfying $\mathcal{P}(2z)=f(\mathcal{P}(z))$, where $\mathcal{P}$ is the Weierstrass elliptic function coming from a certain lattice in $\mathbb{C}^2$. It was thought to be the first such example. However, an example based on Jacobi elliptic function appeared in 1898 in the PhD thesis of Lucjan Emil B\"ottcher, Beitr\"age zu der Theorie der Iterationsrechnung, published by Oswald Schmidt, Leipzig, pp.78, and another one was given in his paper in Polish, Zasady rachunku iteracyjnego (cz\c e\'s\'c pierwsza i cz\c e\'s\'c druga) [Principles of iterational calculus (part one and two)], {\it Prace Matematyczno - Fizyczne}, vol. X (1899 - 1900), pp. 65 - 86, 86-101.
