In 1740 Maclaurin divided with Leonhard Euler and Daniel Bernoulli the prize offered by the French Academy of Sciences for an essay on tides.
The influence of Schleiermacher, whose pupil Leonhard Usteri in his Entwickelung der paulinischen Lehrbegriffs (1824) expressed strong doubts as to Ephesians, carried weight.
The director, Schmalfuss, encouraged him in his mathematical studies by lending him books (among them Leonhard Euler's works and Adrien Marie Legendre's Theory of Numbers), which Riemann read, mastered and returned within a few days.
At the age of nineteen he communicated to Leonhard Euler his idea of a general method of dealing with "isoperimetrical" problems, known later as the Calculus of Variations.
His development of the equation x m +- px = q in an infinite series was extended by Leonhard Euler, and particularly by Joseph Louis Lagrange.
In this they were completely successful, for they obtained general solutions for the equations ax by = c, xy = ax+by+c (since rediscovered by Leonhard Euler) and cy 2 = ax e + b.
Continued fractions, one of the earliest examples of which is Lord Brouncker's expression for the ratio of the circumference to the diameter of a circle (see Circle), were elaborately discussed by John Wallis and Leonhard Euler; the convergency of series treated by Newton, Euler and the Bernoullis; the binomial theorem, due originally to Newton and subsequently expanded by Euler and others, was used by Joseph Louis Lagrange as the basis of his Calcul des Fonctions.

A little later Janus Cornarius or Hagenbut (150o-1558) and Leonhard Fuchs (1501-1566) in Germany, and John Kaye of Caius (1510-1572) in England, carried on the work.
LEONHARD HUTTER (1563-1616), German Lutheran theologian, was born at Nellingen near Ulm in January 1563.
These equations were found by d'Alembert from two principles - that a rectangular canal, taken in a mass of fluid in equilibrium, is itself in equilibrium, and that a portion of the fluid, in passing from one place to another, preserves the same volume when the fluid is incompressible, or dilates itself according to a given law when the fluid is elastic. His ingenious method, published in 1752, in his Essai sur la resistance des fluides, was brought to perfection in his Opuscules mathematiques, and was adopted by Leonhard Euler.
Two methods are employed in hydrodynamics, called the Eulerian and Lagrangian, although both are due originally to Leonhard Euler.
A rigorous demonstration was wanting for many years, Leonhard Euler's proof for negative and fractional values being faulty, and was finally given by Niels Heinrik Abel.
He was as keen in his resentments as he was ardent in his friendships; fondly attached to his family, he yet disliked a deserving son; he gave full praise to Leibnitz and Leonhard Euler, yet was blind to the excellence of Sir Isaac Newton.
With a success equalled only by Leonhard Euler, Daniel Bernoulli gained or shared no less than ten prizes of the Academy of Sciences of Paris.
In 1774 he published a French translation of Leonhard Euler's Elements of Algebra.

His memoir (1775) on the rotatory motion of a body contains (as the author was aware) conclusions at variance with those arrived at by Jean le Rond, d'Alembert and Leonhard Euler in their researches on the same subject.
JOHANN LEONHARD HUG (1765-1846), German Romarr Catholic theologian, was born at Constance on the 1st of June 1765.

He was followed by other writers, - Leonhard Fuchs, whose Historia Stirpium (Basel, 1542) is worthy of special note for its excellent woodcuts; Hieronymus Bock, whose Kreutter Buch appeared in 1539; and William Turner, "The Father of English Botany," the first part of whose New Herbal, printed in English, was issued in 1551.
In 1764 Leonhard Euler employed the functions of both zero and integral orders in an analysis into the vibrations of a stretched membrane; an investigation which has been considerably developed by Lord Rayleigh, who has also shown (1878) that Bessel's functions are particular cases of Laplace's functions.
"The main results," says Leonhard Schmitz, "arrived at by the inquiries of Niebuhr, such as his views of the ancient population of Rome, the origin of the plebs, the relation between the patricians and plebeians, the real nature of the ager publicus, and many other points of interest, have been acknowledged by all his successors."
Walter (1827), but was immediately superseded by the translation of the second edition by Julius Hare and Connop Thirwall, completed by William Smith and Leonhard Schmitz (last edition, 1847-1851).
Leonhard Euler took up the subject several times during his life, effecting mainly improvements in the theory of the various series.
On the death of Count Leonhard (12th April 1500) the fief reverted to the house of Habsburg.
Leonhard Euler, in his paper on curvature in the Berlin Memoirs for 1760, had considered, not the normals of the surface, but the normals of the plane sections through a particular normal, so that the question of the intersection of successive normals of the surface had never presented itself to him.
The earliest known descriptions of the foxglove are those given by Leonhard Fuchs and Tragus about the middle of the 16th century, but its virtues were doubtless known to herbalists at a much remoter period.
Leonhard Euler in 1747 had suggested that achromatism might be obtained by the combination of glass and water lenses.
He entrusted the business to Leonhard Koppe of Torgau, and the rescue was safely carried out(4th of April 1523).
The German botanist, Leonhard Rauwolf (d.
John Dollond, to whom the Copley medal of the Royal Society had been the first inventor of the achromatic telescope; but it was ruled by Lord Mansfield that" it was not the person who locked his invention in his scrutoire that ought to profit for such invention, but he who brought it forth for the benefit of mankind."3 In 1747 Leonhard Euler communicated to the Berlin Academy of Sciences a memoir in which he endeavoured to prove the possibility of correcting both the chromatic and.
James Gregory and Leonhard Euler arrived at the correct view from a false conception of the achromatism of the eye; this was determined by Chester More Hall in 1728, Klingenstierna in 1754 and by Dollond in 1757, who constructed the celebrated achromatic telescopes.
Leonhard Euler (Acta Petrop. 1784) showed that the same hypocycloid can be generated by circles having radii of; (a+b) rolling on a circle of radius a; and also that the hypocycloid formed when the radius of the rolling circle is greater than that of the fixed circle is the same as the epicycloid formed by the rolling of a circle whose radius is the difference of the original radii.
Archbishop Leonhard II., who expelled the Jews from Salzburg in 1498, had to face a conspiracy of the nobles and was besieged in Hohen-Shlzburg by the inhabitants in 151i.
Competent judges have compared him to Leonhard Euler for his range, analytical power and introduction of new and fertile theories.
The problem set was "to perfect in one important point the theory of the movement of a solid body round an immovable point," and her solution added a result of the highest interest to those transmitted to us by Leonhard Euler and J.
