 The development of the book was terminated by Bernoulli 's death in 1705 ; thus the book is essentially incomplete when compared with Bernoulli 's original vision . The quarrel with his younger brother Johann , who was the most competent person who could have fulfilled Jacob 's project , prevented Johann to get hold of the manuscript . Jacob 's own children were not mathematicians and were not up to the task of editing and publishing the manuscript . Finally Jacob 's nephew Niklaus , 7 years after Jacob 's death in 1705 , managed to publish the manuscript in 1713 .
