The Times obituary referred to: "his energy, enthusiasm, and cultured mind" which:
"did much to stimulate the study of international law in days when it needs to be studied more severely than ever, and it may well be that, in the perspective that finally tests the authority of jurists, his labours will secure a permanent place."
