Bernoulli number

1834

According to Knuth a rigorous proof of Faulhaber's formula was first published by Carl Jacobi in 1834.

1842

Ada Lovelace's note G on the Analytical Engine from 1842 describes an algorithm for generating Bernoulli numbers with Babbage's machine.

1880

 −  = 2 × . ==A combinatorial view: alternating permutations== Around 1880, three years after the publication of Seidel's algorithm, Désiré André proved a now classic result of combinatorial analysis.

1893

Solving for B^{\mp{}}_m gives the recursive formulas \begin{align} B_m^{-{}} &= \delta_{m, 0} - \sum_{k=0}^{m-1} \binom{m}{k} \frac{B^{-{}}_k}{m - k + 1} \\ B_m^+ &= 1 - \sum_{k=0}^{m-1} \binom{m}{k} \frac{B^+_k}{m - k + 1}. \end{align} === Explicit definition === In 1893 Louis Saalschütz listed a total of 38 explicit formulas for the Bernoulli numbers, usually giving some reference in the older literature.
