Farther down the property he built the imposing research facilities of Andrew Martin Laboratories. There was a little trouble with the zoning authorities about that, because this was supposed to be a quiet residential area and the research center that Andrew wanted to set up would be the size of a small university campus. There was also, perhaps, some lingering anti-robot feeling at work among the opposition.
But when his application came up for approval, Andrew's lawyer simply said, "Andrew Martin has given the world the prosthetic kidney, the prosthetic lung, the prosthetic heart, the prosthetic pancreas. In return all he asks is the right to continue his research in peace on the property where he has lived and worked for well over a hundred years. Who among us would refuse such a small request when it comes from so great a benefactor of mankind?" And after a certain amount of debate the zoning variance was granted and the buildings of the Andrew Martin Laboratories Research Center began to rise amid the somber cypresses and pines of what had, long ago, been the wooded estate of Gerald Martin.
Every year or two, Andrew would return to the gleaming operating theater at u. S. Robots for additional prosthetic upgrading of his own. Some of the changes were utterly trivial ones: the new fingernails and toenails, for example, virtually indistinguishable now from those of humans. Some of the changes were major: the new visual system, which although synthetically grown was able to duplicate the human eyeball in virtually every respect.
"Don't blame us if you come out of this permanently blind," Magdescu told him sourly, when Andrew went to him for the eye transplant.
"You aren't looking at this rationally, my friend," replied Andrew. "The worst that can happen to me is that I will be forced to go back to photo-optic cells. There is no risk whatever that I will suffer complete loss of eyesight."
"Well-" Magdescu said, and shrugged.
Andrew was right, of course. No one was forced to be permanently blind any more. But there were artificial eyes and then there were artificial eyes, and the photo-optic cells that had been a feature of Andrew's original android body were replaced with the new synthetic-organic eyes that Andrew Martin Laboratories had perfected. The fact that hundreds of thousands of aging human beings had been content for more than a generation to use photo-optic cells was irrelevant to Andrew. To him they looked artificial; they looked inhuman. He had always wanted true eyes. And now he had them.
Magdescu, after a while, gave up protesting. He had come to see that Andrew was destined to have his way in all things and that there was no point in raising objections to Andrew's schemes for new prosthetic upgrades. Besides, Magdescu was beginning to grow old now, and much of the fire and zeal that had been characteristic of him when Andrew first came to him had gone out of him by now. Already he had had several major prosthetic operations himself-a double kidney replacement, first, and then a new liver. Soon Magdescu would reach retirement age.
And then, no doubt, he would die, in ten or twenty years more, Andrew told himself. Another friend gone, swept away by the remorseless river of time.
Andrew himself, naturally, showed no signs of aging at all. For a time that troubled him enough that he debated having some cosmetic wrinkles added-a touch of crow's feet around his eyes, for example-and graying his hair. After giving the matter a little thought, though, he decided that to go in for such things would be a foolish affectation. Andrew did not see his upgrades that way at all: they represented his continued attempt to leave his robot origins behind and approach the physical form of a human being. He did not deny to himself that it had become his goal to do that But there was no sense in becoming more human than the humans themselves. It struck him as pointless and absurd to subject his ever-more-human but still ageless android body to the external marks of aging.
Vanity had nothing to do with Andrew's decision-only logic. He was aware that humans had always tried to do everything in their power to conceal the effects that growing old had on their appearance. Andrew realized that it would be altogether ridiculous for him, exempted as he was from aging by his inherent android nature, to go out of his way deliberately to take those effects upon himself.
So he remained ever youthful-looking. And, of course, there was never any slackening of his physical vigor: a careful maintenance program made certain of that But the years were passing, and passing swiftly now. Andrew was approaching the one hundred and fiftieth anniversary of his construction.
By this time Andrew was not only exceedingly wealthy but covered with the honors that Alvin Magdescu had foretold for him. Learned societies hastened to offer him fellowships and awards-in particular one society which was devoted to the new science he had established, the one he had called robobiology but which had come to be termed prosthetology. He was named its honorary president for life. Universities vied with one another to give him degrees. An entire room in his house-the one upstairs that once had been his woodworking studio, five generations before-was given over now to storing the myriad diplomas, medals, scrolls of honor, testimonial volumes, and other artifacts of Andrew's worldwide status as one of humanity's greatest benefactors.
The desire to recognize Andrew's contribution became so universal that he needed one full-time secretary simply to reply to all the invitations to attend testimonial banquets or accept awards and degrees. He rarely did attend any such ceremonies any longer, though he was unfailingly courteous in refusing, explaining that the continued program of his research made it inadvisable for him to do a great deal of traveling. But in fact most of these functions had come to irritate and bore him.
