The following is a list of good-sized Wallace obituaries that appeared after his death. From some of these I have drawn short quotations that give some indication of the kind of esteem felt for Wallace at the end of his life.

Important:  The entries are followed, as possible or relevant (many of the pdfs are drawn directly or indirectly from the original hardcopy volumes), by their sources, coded by the source database and the institutional source of the original scans.  Codes for the databases are:  BHL (Biodiversity Heritage Library), CDL (Cornell Digital Library), GB (Google Books), HT (HathiTrust Digital Library, IA (Internet Archive), and TR (Trove, National Library of Australia).  Institutional codes should be self-evident.

• Athenæum no. 4490 (15 Nov. 1913): 564a-564b 'Alfred Russel Wallace' (anon.). "Wallace's contributions to science could scarcely be over-estimated; and they are considerable even without the results of what has been called the creative vividness with which the idea of natural selection came to him after reading Malthus's 'Principles of Population.'"
• Auk 31(1) (Jan. 1914): 138-141 (anon.). "Wallace, while standing in the highest rank among ornithologists, entomologists and botanists is best known in the broader field of philosophy and evolutionary thought."

Chesterton remarked that if he was asked what great man would be regarded as the most important and significant figure in the nineteenth century he would hesitate between Walt Whitman and Alfred Russel Wallace. And Mr. Chesterton went on to make it clear that he regarded the great scientist as one of the giants of the wonderful century because he was the leader of a revolution and a counter revolution; the first was the Darwinian movement, the other the movement of psychical research."

• The Clarion (London) no. 1145 (14 Nov. 1913): 2a-2b (Harry Lowerison). "Now lies he there, and all are glad to give him reverence, for that with the weapons he had and the limitations he laboured under he fought as a man should fight for the truths it was given to him to see. If among those truths some error found its way, why trouble? He did a man's work manfully, and now he has won his peace. On the whole the world is better, sweeter, cleaner, nobler, for our great comrade's life in it."

". . . his heterodoxy brought upon him a liberal measure of abuse and ridicule from the hidebound of his own country and ours; but like Ruskin, he never recanted or compromised in the face of obloquy. His life has been a long and noble service to humanity, performed in a spirit of modest self-effacement as rare almost as the achievement itself."

• The Geographical Journal 43(1) (Jan. 1914): 88-92 'Alfred Russel Wallace, O.M.' (Henry O. Forbes). "By the death of Alfred Russel Wallace, on November 7 last, at the age of ninety years, the Royal Geographical Society, to which he was elected in 1854, loses one of its oldest and most distinguished Fellows; and Natural Science, especially in its biogeographical aspect, one of those who have, in most widely extending its boundaries and deeply influencing the thought of his time, achieved a name which will live as long as Natural Knowledge is cultivated."

"With the death of Alfred Russel Wallace there disappears the last of that great breed of men with whose names the glory of the Victorian era is inseparably bound up. . . in ranking him among the truly notable figures of his generation, one thinks not so much of his most famous achievement, but rather of the wide sweep of his scientific labors, the freshness and originality of his outlook, the vigor and energy of his attack on all manner of questions relating to man and society, and a certain quality of largeness which marks his style . . ."

In addition to the preceding, I have it on good authority (but have not had time to personally verify) that obituary notices appeared within days of his death (on 7 November 1913) in the following foreign newspapers: La Bataille Syndicaliste (Paris), Le Figaro (Paris) (8-11-13), Le Petit Bleu (Paris) (9-11-13), Le Temps (Paris) (9-11-13), L'Action (Paris) (9-11-13), L'Intransigeant (Paris) (9-11-13), Berliner Tageblatt (Berlin) (8-11-13), and Vossische Zeitung (Berlin) (8-11-13). Doubtlessly there were many others as well.
