Henryk Fryderyk Hoyer

Henryk Fryderyk Hoyer (also Heinrich Friedrich Hoyer , born April 26, 1834 in Inowraclaw , † July 3, 1907 in Warsaw ) was a Polish physician and is considered the father of Polish histology .

Life

Henryk Fryderyk Hoyer came from a Polish-German family and was the son of the pharmacist Ferdynand Hoyer.

Hoyer attended grammar school in Bromberg , studied medicine at the University of Breslau and the Friedrich Wilhelms University in Berlin, and received his doctorate in Berlin in 1857 . In 1858 he passed the medical state examination and became assistant to Karl Bogislaus Reichert at the University of Breslau . In 1859, on the recommendation of Reichert, who had accepted a call to Berlin, he became a member of the Medical and Surgical Academy in Warsaw , where he initially worked as an associate professor and in 1862 as a full professor of embryology and histology at the newly founded Warsaw secondary school .

After 1869 and the conversion of the secondary school into the Imperial University of Warsaw, he had to do a doctoral thesis again, as extensive knowledge of the Russian language and a previous graduation from a Russian university were now inevitable. In 1871 he received his doctorate at the St. Vladimir University in Kiev and on his return was appointed full professor of embryology, histology and comparative anatomy. From the 1880s onwards, an eye disease prevented him from working with the microscope. In June 1895 he finished his activity at the University of Warsaw and became emeritus.

Henryk Fryderyk Hoyer published his Histologia ciała ludzkiego in 1862, the first modern textbook on histology in the Polish language. He opened the first histological laboratory in Poland and was the first to provide evidence of arterio-venous anastomoses on the basis of histological methods carried out in 1877 . The term Hoyer-Grosser organs ( glomus cutaneum ) for these ball-like arterio-venous anastomoses is named after him and Otto Grosser , who published important additions to Hoyer's observations in 1902.

Besides Zygmunt Laskowski , his students also include Józef Nussbaum-Hilarowicz (1859–1917) and Eduard Strasburger .

On December 5, 1883 he was registered as Heinrich Friedrich Hoyer under matriculation no. Elected a member of the Leopoldina in 2424 .

In 1900 he was awarded an honorary doctorate from the Jagiellonian University in Krakow .

He was awarded the Russian Order of Saint Stanislaus and the Russian Order of Saint Anne (2nd grade).

Hoyer published a total of around 100 scientific writings in Polish, Russian and German.

He was married to his wife Ludwika, née Werner. The anatomist Henryk Ferdynand Hoyer (1864–1947) was the couple's son.

Henryk Fryderyk Hoyer was buried in Warsaw in the Evangelical-Augsburg Cemetery .
