Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, ''De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for observ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Fructibus Et Seminibus Plantarum
''De Fructibus et Seminibus Plantarum'', also known by its standard botanical abbreviation ''Fruct. Sem. Pl.'', is a three-volume botanic treatise by Joseph Gaertner. The first volume was published in December 1788. The second volume was published in four parts, in 1790, 1791, 1791 and 1792 respectively. A third volume was published after Gaertner's death by his son Karl Friedrich von Gaertner from 1805 to 1807; this final volume is also known as Supplementum Carpologicae, abbreviated as ''Suppl. Carp.''. Most of the illustrations for the work were done by Johann Georg Sturm (1742-1793). ''De Fructibus'' was based on specimens of over a thousand genera, including Australian and Pacific specimens from the collection of Sir Joseph Banks, and South African specimens from the collection of Carl Peter Thunberg. It was essentially a study of fruits and seeds, but the resultant classification was outstanding for its time. Julius von Sachs claimed that the work "forms an epoch in the his ...

Jacob Sturm
Jacob Sturm (21 March 1771 – 28 November 1848) was a leading engraver of entomological and botanical scientific publications in Germany at the end of the 18th and beginning of the 19th century. He was born and lived in Nuremberg and was the only son of engraver Johann Georg Sturm (1742-1793), who trained him in drawing and copperplate engraving. Sturm became a celebrated insect collector and founded the Nuremberg Society for Natural History. His entomological and botanical plates are very accurately drawn and show minute details and enjoyed a great popularity among naturalists. As most of his works were published in a small format, they could be purchased by a larger public and they were very popular. During this period, Nuremberg was the centre of natural history book production in Germany. "The book ''Deutschlands Flora'',lit.: ''Germany's flora in pictures from nature with descriptions. Nuremberg, printed at the expense of the author'' 1798–1862. 163 parts (in 136 vol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botanical Illustrators
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", "herbs" "grass", or "fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, medici ...
