Biography
Johann Zacherl was born in Munich (Germany) in 1814 and died in Vienna (Austria) in 1888. After finishing his studies, he left Munich to visit successively Vienna, St Petersburg and Odessa down to Tiflis in the Caucasus. There, he discovered that local villagers used a natural insecticide, Pyrethrum, against vermin and began to develop its trade with Austria in 1842. This powder received different names: Lowizachek in Armenia, Bug Flower, Powder of Persia and Persian insect powder.
After a longer stay in Tiflis, he established in Vienna his company in 1855, the Mottenfraß-Versicherungsunternehmung Johann Zacherl, in the 19th district and started to sell the famous insect repellent Zacherlin. With the help of his skillful son Johann Evangelist Zacherl, he developed the Pyrethrum product line around the insecticide powder.

Famous quotes containing the word biography:
“A biography is like a handshake down the years, that can become an arm-wrestle.”
—Richard Holmes (b. 1945)
“In how few words, for instance, the Greeks would have told the story of Abelard and Heloise, making but a sentence of our classical dictionary.... We moderns, on the other hand, collect only the raw materials of biography and history, “memoirs to serve for a history,” which is but materials to serve for a mythology.”
—Henry David Thoreau (1817–1862)
“Had Dr. Johnson written his own life, in conformity with the opinion which he has given, that every man’s life may be best written by himself; had he employed in the preservation of his own history, that clearness of narration and elegance of language in which he has embalmed so many eminent persons, the world would probably have had the most perfect example of biography that was ever exhibited.”
—James Boswell (1740–95)
