Leopold Ruzicka was born on September 13, 1887, in Vukovar, a small Croatian town on the Danube, his father a cooper by trade was Croatian and his mother German. Following the death of his father in 1891, he lived with his mother in Osijek and attended the classics-program secondary school in Osijek. He was a fairly good student but really only showed any interest in physics and mathematics, other subjects left him unfulfilled. There was no chemistry in the curriculum but he developed a great personal interest in the composition of natural products.  In 1906 he went to the Technische Hochschule at Karlsruhe, Germany, where he began his chemical studies.

In 1916 he received the support of the oldest perfume manufacturer in the world Haarman & Reimer, of Holzminden in Germany and became a Swiss citizen in 1917.  In 1921 the Geneva perfume manufacturers Chuit & Naef asked him to collaborate where his most fruitful work began by establishing the structure and synthesis of alicyclic ketones and Terpenes: the primary constituents of the essential oils of many types of plants and flowers. Essential oils are used widely as fragrances in perfumery, medicine and aromatherapy. By conducting research on the naturally occurring musk perfumes, civetone from the civit cat and muscone, the molecule responsible for the smell of musk, he provided the fragrance industry with a valuable source of new raw materials. The perfume industry required such large supplies of muscone, which could only be prepared from the musk gland of musk deer, it probably saved the musk deer from extinction. The Synthesis of these molecules and their derivatives transformed the perfume industry providing it with an even greater variety of aromas.

In the 1930s he unravelled the molecular structure of the sex hormones androsterone (1934), progesterone (1934), and testosterone (1935). His laboratory became the world centre for organic chemistry.

During World War II he was a founding member of the Swiss-Yugoslav Relief Society, and worked to rescue Jewish scientists from Nazi Germany. He was later politically active in protests against the accumulation of atomic weapons.

In 1939, he won the Nobel Prize for chemistry with Adolf Butenandt.

Carl Zeiss – Noted German Scientist and Optician – Birthday


Carl Zeiss – 11th September 1816 –  3rd December 1888 – noted German scientist and optician known for the lens manufacturing company he founded, called Carl Zeiss.

CarlZeissCarl Friedrich Zeiss, born on 11 September 1816 in Weimar was the fifth of 12 children. He attended the local high school where he showed a keen interest in technology. On passing a special graduation exam he went on to study natural sciences the University of Jena.

In 17 November 1846 he opened his own business building and repairing scientific instruments while selling telescopes, microscopes, and other scientific devices purchased from dealers. In 1847 Zeiss began to produce simple microscopes. Business fared well and he moved into larger premises on 1 July 1847.

Zeiss began to focus his production activities on microscopes. In his workshop, he attached central importance to quality and precision. Any microscopes his staff made that did not meet his exacting standards he would shatter with his own hands in front of them on the company anvil.

Carl Zeiss is also held in high regard as one of the pioneers of social insurance: the Zeiss medical insurance program, founded in 1875 was set up to guarantee employees free medical treatment and free medication in the event of illness.

Zeiss’ collaboration with Otto Schott commenced in 1882, developing and manufacturing new types of optical glass and instrumentation in Jena.

Following a series of strokes Carl Zeiss sadly passed away in Jena on 3 December 1888. To this day the Carl Zeiss lenses are held in high regard for many applications including digital cameras, telescopes and microscopes.

To find out more about lenses and their applications look at our website www.ecolifegizmos.co.uk. We have kits for building telescopes or explore the relationship between a telescope and microscope with our super telescope/ microscope pen alternatively try our Mono-Periscope to spy around corners.

Encouraging Children to Clean Their Teeth


Rather than force your child with a tooth brush try this poem

My name’s (child’s name)  and I’ve got no teeth
I speak with a whistle and look like a thief
Having no teeth is not much fun
For when I smile out slips my tongue

I have more verses.
