The bicycle in this somewhat ineptly titled autobiography plays but a small part in the career of its 80-year-old author. Indeed, as he has spent most of his life and his entire medical career on Long Island, a better title might be ""Doctor on Long Island"". Born in New York City in 1878, taken at the age of 8, when his father died, to Patchogue, L.I., the author grew up in that town, graduating at the age of 16 from its high school and the same year entering the New York Medical School (Flower Hospital). In 1901 he opened an office as a general practitioner in Bay Shore, L.I., where he is still living. At first, encountering an astonishing amount of enmity from established doctors and too poor to buy a horse and buggy to compete with them, he bought a bicycle, an excellent investment enabling him to make calls more quickly than rivals dependent on horse-power; the bicycle long since has been replaced by automobiles and his first office, by his own hospital. Pleasantly written but at times in a somewhat monotonous and too- slick style hinting of the ghost (no ghost is mentioned in the text, however), this story of a long, successful and not too spectacular medical career (among other achievements, the author has delivered some 5000 babies) is of little scientific value but it should hold a built-in appeal to the originals, families and friends of the babies, to Long Islanders in general, and to readers of casual medical autobiography in many other parts of the country.
