His age was debated, and so was his origin. Most people thought he was "about forty"; a very safe age, young enough to allow of almost unlimited expectation, old enough to make results achieved not quite unnatural, though possibly startling. Yes, he must be "about forty." And his origin? "Meyer" suggested Germany. As to "Isaacson," it allowed the ardent imagination free play over denationalized Israel. Someone said that he "looked as if he came from the East," to which a cynic made answer, "The East End."

There was, perhaps, a hint of both in the Doctor of Cleveland Square. Certain it is that in the course of a walk down Brick Lane, or the adjacent thoroughfares, one will encounter men of his type; men of middle height, of slight build, with thick, close-growing hair strongly curling, boldly curving lips, large nostrils, prominent cheek-bones, dark eyes almost fiercely shining; men who are startlingly un-English. Doctor Meyer Isaacson was like these men. Yet he possessed something which set him apart from them. He looked intensely vital--almost unnaturally vital--when he was surrounded by English people, but he did not look fierce and hungry. One could conceive of him doing something bizarre, but one could not conceive of him doing anything low. There was sometimes a light in his eyes which suggested a moral distinction rarely to be found in those who dwell in and about Brick Lane. His slight, nervous hands, dark in colour, recalled the hands of high-bred Egyptians. Like so many of his nation, he was by nature artistic. An instinctive love of what was best in the creations of man ran in his veins with his blood. He cared for beautiful things, and he knew what things were beautiful and what were not. The second-rate never made any appeal to him. The first-rate found in him a welcoming enthusiast. He never wearied of looking at fine pictures, at noble statues, at bronzes, at old jewelled glass, at delicate carvings, at perfect jewels. He was genuinely moved by great architecture. And to music he was almost fanatically devoted, as are many Jews.
