The innate reticence and shyness of manner which were noticeable all through his life covered a large-heartedness even in the most careful observation of facts, and produced a tolerant disposition towards his fellow-men even when he most disagreed with their views or dogmas.  He was one of those of whom it may be truly said in hackneyed phrases that he was “born great,” whilst destined to have “greatness thrust upon him” in the shape of honours which he received with hesitation.

From his autobiography we gather that his father, though dimly tracing his descent from the famous Wallace of Stirling, was born at Hanworth, in Middlesex, where there appears to have been a small colony of residents bearing the same name but occupying varied social positions, from admiral to hotel-keeper—­the grandfather of Alfred Russel Wallace being known as a victualler.  Thomas Vere Wallace was the only son of this worthy innkeeper; and, being possessed of somewhat wider ambitions than a country life offered, was articled to a solicitor in London, and eventually became an attorney-at-law.  On his father’s death he inherited a small private income, and, not being of an energetic disposition, he preferred to live quietly on it instead of continuing his practice.  His main interests were somewhat literary and artistic, but without any definite aim; and this lack of natural energy, mental and physical, reappeared in most of the nine children subsequently born to him, including Alfred Russel, who realised that had it not been for the one definite interest which gradually determined his course in life (an interest demanding steady perseverance and concentrated thought as well as physical enterprise), his career might easily have been much less useful.

It was undoubtedly from his father that he acquired an appreciation of good literature, as they were in the habit of hearing Shakespeare and similar works read aloud round the fireside on winter nights; whilst from his mother came artistic and business-like instincts—­several of her relatives having been architects of no mean skill, combining with their art sound business qualities which placed them in positions of civic authority and brought them the respect due to men of upright character and good parts.

During the chequered experiences which followed the marriage of Thomas Vere Wallace and Mary Ann Greenell there appears to have been complete mutual affection and understanding.  Although Wallace makes but slight reference to his mother’s character and habits, one may readily conclude that her disposition and influence were such as to leave an indelible impression for good on the minds of her children, amongst her qualities being a talent for not merely accepting circumstances but in a quiet way making the most of each experience as it came—­a talent which we find repeated on many occasions in the life of her son Alfred.

It is a little curious that each of these great scientists should have been born in a house overlooking a well-known river—­the home of the Darwins standing on the banks of the Severn, at Shrewsbury, and that of the Wallaces a stone’s throw from the waters of the romantic and beautiful Usk, of Monmouthshire.
