Historical Introduction The Marfan Syndrome: From Clinical Delineation to Mutational Characterization, a Semiautobiographic Account VictorA. McKusick l n 1876, E. Williams, an ophthalmologistin Cincinnati, Ohio, described ectopia lentis in a brother and sister who were exceptionally tall and had been loosejointed from birth. I Although there is a Williams syndrome that has aortic manifestations (supravalvar aortic stenosis), the name Williams was never associated with the disorder we now call Marfan syndrome. The reason is clear: Williamswas geographically removed from the leading medical centers and published in the Transactions of the American Ophthalmological Society; surely his report attracted little attention and the non-ocular features were not emphasized. 2 The case report that brought the disorder to attention was provided by a prominent PariÂ sian professor of pediatrics, Antoine Bernard-Jean Marfan (1858-1942), who did much to establish pediatrics as a specialty in France and elsewhere. He was the author of widely read textbooks and monographson pediatrictopics and waseditor of Le Nourrisson for a great many years. In addition to the syndromeunder discussion here, his name is often attached to "Marfan's law" (that immunity to pulmonary phthisis is conferred by the healing of a local tuberculous 3 lesion) and Marfan's subxiphoid approach for aspiratingfluid from the pericardial sac. (Please pardon my use of the possessive form of the eponym in these two instances!) Pictures of Marfan (Fig.
The developments in mass spectrometry over the past fifteen years have been impressive in their implications in bioanalytical chemistry. The achievements begin with the inventions of Cf-252 Plasma Desorption Mass Spectrometry by Macfarlane and Fourier Transform Mass Spectrometry by Comisarow and Marshall in the mid 1970s. The former showed the feasibility of producing large gas-phase ions from large biomolecules whereas the latter enhanced the capabilities for ion trapping especially in analytical mass spectrometry. A major achievement was the development by Barber of Fast Atom Bombardment (FAB) mass spectrometry, an advance that heralded a new era in biological mass spectrometry. Contemporary and routine instruments such as magnetic sectors and quadrupoles were rapidly adapted to F AB, and nearly the entire universe of small molecules became amenable to study by mass spectrometry. The introduction of FAB also paved the way for improvement of instrument capability. For example, the upper mass limit of magnet sector mass spectrometers was increased by nearly an order of magnitude by the instrument manufacturers. Furthermore, the technique of tandem mass spectrometry (MS/MS) was given new meaning because important structural information for biomolecules could now be produced for ions introduced by FAB into the tandem instrument. The evolution of MS/MS continues today with the development of ion traps, time-of-flight, and sector instruments equipped with array detection.
