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.

• American Museum Journal 13 (Dec. 1913): 330-333 'A great naturalist; Alfred Russel Wallace, 1823-1913' (Henry Fairfield Osborn). (link to the Google Book Search database)
• Athenæum no. 4490 (15 Nov. 1913): 564a-b '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."
• Berliner Morgenpost 8 Nov. 1913 (anon.).
• British Medical Journal (London) no. 2759 (15 Nov. 1913): 1338-1339 (anon.). "A life so long, so active, and so varied, cannot be dealt with in a small compass. Simple and unostentatious, he was a great man in the truest sense of the word."
• Bulletin of the American Geographical Society 46(1) (1914): 54 (anon.). (link to the JSTOR database)
• The Christian Commonwealth 12 Nov. 1913: 112d-112e 'The last of the Victorians; Death of Dr. Alfred Russel Wallace' (anon.). "Long ago Mr. G. K. 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 Church Times (London) 14 Nov. 1913: 663d (anon.).
• 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."
• Current Opinion (New York) 56(1) (Jan. 1914): 32-33 'Passing of one of the supreme figures in modern science' (anon.). "Only a great ruler could have been accorded by the press of the world any such elaborate obituary recognition as was evoked by the death of Alfred Russel Wallace . . . "

• The Daily Graphic (London) 8 Nov. 1913. (anon.).

• The Dial (Chicago) 55(698) (16 Nov. 1913): 416 (anon.). ". . . 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). (link to the JSTOR database) "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."

There is something curiously static in the aspect of human lives in retrospect. They take and keep their places in a portrait gallery. Alfred Russel Wallace will live in the biographical page as an untiring personality, pushing on."

• Nation (U.S.) 97(2524) (13 Nov. 1913): 452-453 'The last of the Victorians' (anon.). "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 . . ."
• Nature 92(2298) (13 Nov. 1913): 322 'Dr. Alfred Russel Wallace, O.M., F.R.S.' (anon.). ". . . it was peculiarly his-- 'To see the world in a grain of sand, And heaven in a flower; To grasp infinity in the palm of the hand, And eternity in an hour.'"

His activities covered such a long period, and were so varied, that no one living is in a position to critically appreciate more than a part of them . . . All must agree that a great and significant career has just been closed, but its full measure will probably never be known to any single man."

• Socialist Review 12 (Jan. 1914): 15-16 'Alfred Russel Wallace' ('The Editor').

"He never yielded to the subtle inference that man is a clod, ephemeral and helpless, the sport of circumstances, or a miserable worm whose only hope was in some external power. His message was the inspiring one that every man had the means of rising out of his low estate to the heights of the gods."

[submitted by Christine Garwood] ". . . his researches and theories will go down to posterity as the most serious and important of all attempts to raise the veil that enshrouds the vast abstract thing which men call the 'Universe' . . . But Alfred Russel Wallace has not finished his work for his fellows. He will remain amongst us, he will still inspire us, he has still other and greater messages for the world."

"Thinking of Wallace's happy, strenuous life, we are led to realize man's independence of wealth and circumstance, to know by his example that, if it be great enough, 'the mind is its own place,' and is 'not to be changed by place or time.'"

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.
