galvanometer by compa-ring the original technique of Waller, employing Lippmann’s capillary galvanometer,
and the results of his own improvement of this method with the tracings obtained with the new de-vice. His
report is illustrated with the first modern ECG recording and with the customary P, Q,R,S,T notation. Einthoven
was born in Semarang, Java, in 1860. When he was six years of age his father, a physician, died and the family
moved to Utrecht. There Einthoven entered medical school in 1879 and received his degree in medicine with
distinction six years later. He was appointed professor of physiology in Leiden in 1886. Stimulated by the work
of Au-gustus Waller, he started to improve on the techniques for recording the electrical signals of heartbeat. His
work not only improved previous methods but eventually also led to the deve-lopment of a new instrument, the
string galvanometer, for which he received the Nobel Prize in Medicine in 1924. He died in 1927.- Gedeon.

Willem Einthoven (1860 – 1927) was a Dutch doctor and physiologist. He invented the first practical electrocardiogram
(ECG or EKG) in 1903 and received the Nobel Prize in Medicine in 1924 for it. Before Einthoven's
time, it was known that the beating of the heart produced electrical currents, but the instruments of the time
could not accurately measure this phenomenon without placing electrodes directly on the heart. Beginning in
1901, Einthoven completed a series of prototypes of a string galvanometer. This device used a very thin filament
of conductive wire passing between very strong electromagnets. When a current passed through the filament, the
electromagnetic field would cause the string to move. A light shining on the string would cast a shadow on a
moving roll of photographic paper, thus forming a continuous curve showing the movement of the string. The
original machine required water cooling for the powerful electromagnets, required 5 people to operate it and
weighed some 600 lb. This device increased the sensitivity of the standard galvanometer so that the electrical
activity of the heart could be measured despite the insulation of flesh and bones. Although later technological
advances brought about better and more portable EKG devices, much of the terminology used in describing an
EKG originated with Einthoven. His assignment of the letters P, Q, R, S and T to the various deflections is still
used. The term "Einthoven's triangle" is named for him. It refers to the imaginary inverted equilateral triangle
centered on the chest and the points being the standard leads on the arms and leg. After his development of the
string galvanometer, Einthoven went on to describe the electrocardiographic features of a number of
cardiovascular disorders. Later in life, Einthoven turned his attention to the study of acoustics, particularly heart
sounds which he researched with Dr. P. Battaerd.

First edition of this compilation of different authors to all sort of devils: a natural history of evil. “The most
curious work of protestant demonology is the Theatrum Diabolorum by Sigmund Feyerabend, a voluminous
collection of the views of Luther’s followers concerning the existence, power, nature and demeanor of devils.
Luther’s belief in the Devil was crude, but he was even here morally great, strong in his religious sentiment, and
serious in his demand that every one personally should honestly wage a war with the powers of evil, and that no
church, no intercession of saints, no formulas or rituals had any saving powers. Luther’s followers retain all the
crudities of their master and to some extent his moral seriousness, but they fall below the manliness of his spirit.
Feyerabend’s Theatrum, which, as the title says, is a useful and sensible book, contains a great number of essays
written by such prominent authorities as Jodocus Hockerus, Hermann Hamelmann, Andreas Musculus, Andreas
Fabricius, Ludovicus Milich, and others. The Reverend Hocker explains in 48 chapters almost all possible
problems connected with devils whose number is [Chapter VII], according to Borrhaus, calculated to be not less
than 2.665.866.746.664. Others describe special kinds of devils, such as the devil of blasphemy, dance-devil, the
servant’s devil, the hunting devil, the drink-devil, the wedlock-devil, the devil of tyranny, the laziness devil, the
devil of unchastity, the miser’s devil, the pride devil, the pantaloon devil, the gambling devil, the courtier’s devil,
and the pestilence devil. The author of the last chapter, Rev. Hermann Strack, concludes by saying: “When we
