Letter to Robert Dreyfus, 10 May 1908: "I've written a few lines about M. Halévy but Beaunier has done it before me, in any case he has the advantage of me, but what I said was perhaps more exact and more unusual, but lacking shape".
Kolb: "Upon learning of the death of Ludovic Halévy he wrote a small obituary. But Le Figaro having already published one by André Beaunier Proust did not attempt to have his article published anywhere else." Corr VIII, p XVI.
