Georges Jacob (1877 - 1950) was a French organist, improviser and composer.
He won a First prize in organ in 1900, in Alexandre Guilmant's class. From 1892 to 1912, G. Jacob gave organ recitals, which were very well attended at the Schola Cantorum de Paris. His aim was to bring out the best of both ancient and modern works of organ literature. In 1922, he succeeded Joseph Bonnet as organist of the Orchestre de la Société des Concerts du Conservatoire.
This is piece number 2 from the 1909 work 'Quatre Morceaux pour Orgue'. The score can be found on IMSLP:
