Fresh, exuberant, tantalizing ""images of Alexander Graham Bell""--starting with the jacket photo of the portly, white-bearded inventor and his long-frocked wife bending toward one another, about to kiss; they have to bend because she is standing inside a tetrahedron. . . of his invention. (No, Buckminster Fuller didn't know that Bell had preceded him, he relates in the introduction, ""until after the geodesic dome."") Dorothy Eber, best known for Pitseolak and other documents of Eskimo life, discovered Bell's manifold activities when she bought a cottage at Baddeck, in Nova Scotia, where the Bells spent long working summers from 1895 until their death five months apart, in 1922. There, he pursued researches in sheep-breeding (would a ewe with more than two teats produce more than one lamb?), in water condensation and desalination (why ""should anyone die of thirst upon the ocean?""), in aeronautics (whence the tetrahedron--devised for kites, intended for a plane) and hydrofoil propulstion. Mrs. Bell provided ""support services,"" technical suggestions, and venture capital. The Bell children and grandchildren soaked up ""the scientific way of thinking."" And the local populace employed in household and workshop, reveled in the excitement. From survivors, we hear of Bell's idiosyncrasies (separate quarters for ""specific trains of thought,"" among them), and Mrs. Bell's high-spirited, unfazed response, despite her long-time deafness. And because picture-taking was both systematic and endemic, there are photos aplenty--of the tetrahedral kites and flying craft, of Bell kite-watching and ""conversing"" with Helen Keller, of the whole bounteous domain. Some superfluous preaching; mostly--delight.
