Ernst Bardey (around 1870)

Ernst August Bardey (born May 21, 1828 in Muchow ; † April 1, 1897 in Bad Stuer ) was a German mathematician and teacher . Bardey was the author of numerous mathematical school and exercise books, some of which are still published today.

Life

Ernst Bardey was a younger son of the pastor Christian Wilhelm Bardey (1776–1843) from his second marriage to Sophie (Elisabeth Catharina Dorothea), geb. von Kossel (1798–1880). Ernst's older brother Gustav Bardey (1826–1905) became a gardener, spa director and leaseholder of the water sanatorium (Bad) Stuer.

Bardey received his school education at the Friedrich-Franz-Gymnasium in Parchim . Only under great financial difficulties, the father had died early, with the help of scholarships and the Konvikt as well as the holding of private lessons, he began to study at the University of Rostock from Easter 1849 . He first studied Protestant theology and later until 1852 mathematics . At Easter 1852 Bardey moved to the Albertus University in Königsberg . There he also began studying physics until 1855 . In Königsberg he attended lectures by Friedrich Julius Richelot and Otto Hesse on mathematics, and with Franz Ernst Neumann on physics. With the latter he conducted a lively correspondence. Because of his severe rheumatism - most likely ankylosing spondylitis  - he had to finish his studies. Almost unable to move, he traveled in April 1855 to the sanatorium in Bad Stuer run by his brother Gustav and later to his home town of Muchow, where he labored until 1861. Even now he could only move with walking aids . After his condition improved, Bardey took over a position as a private tutor in Neu-Stuer and Hoppenrade . Later he went to Brandenburg an der Havel as a private teacher , where Wilhelm August Ernst Bardey (1838–1889), another brother of his, practiced as a dentist.

During his stay there, his first major work, Algebraic Equations , appeared in 1868, along with the results and the methods for their solution, the later editions of which he constantly expanded and which was published again in 2011. His methodically organized collection of exercises, containing more than 7000 exercises, covering all parts of elementary arithmetic for grammar schools, secondary schools and polytechnical schools , appeared for the first time in 1871. The work was later heavily revised and expanded by him and printed in 23 editions while he was still alive. That same year, Bardey published Quadratic Equations. With the solutions for the upper classes of grammar schools and secondary schools . Through private lessons that he gave in Brandenburg and the income from his books, his financial situation improved considerably.

However, his health deteriorated again, so that he was forced to return to Stuer in June 1878. From now on he lived only from the publication of his books. In 1881 he gave arithmetic exercises and a textbook on arithmetic. Preferably for higher middle schools, the fact that it was published again in 1940 was also translated into Spanish. All of his works have been published by Teubner Verlag .

In his final years, Bardey's physical and mental condition continued to deteriorate. He died at the age of 68 in Bad Stuer and was buried next to his mother as requested. After his death, his brother published a self-biography of him in the journal for mathematical and scientific teaching , which lasts until 1858, and added it himself as a necrology .

The grave of him and his mother can still be found in the churchyard in Stuer. On the obelisk of his grave, his brothers had the following saying put for him:

“ LASTLY YOU WENT BROKEN AND BENDED, YOU CANNOT RECOGNIZE THE BOLD QUESTIONER. WHAT YOU FIRSTED, WHAT YOUR SPIRIT AND STRENGTH YOU OWN, WHAT GOOD YOU DONE, YOURS WILL REMAIN UNFORGETTABLE "
