Oh, how I wish Philly was covered in snow like this postcard of Stockholm, Sweden.

It's been a while since we've seen a good old fashioned snow storm here in the city. Maybe I'll sleep with my pajamas on inside out tonight....

Why settle for being just a Baroness-Professor when you can be a Princess-Professor?

Think big, friends! Margarete von Wrangell (1877-1932) was an agricultural chemist and Germany's first female full professor. She married her childhood friend, Prince Vladimir Andronikov, in 1925. This marriage gave her the title of Princess Andronikov, which was a an addition to her title at birth, Baroness von Wrangell.

This article, in German, mentions that the marriage gave her Russian citizenship. Take a peek on our digital collections site.

Liegnitzer Bomben in the Archives!

Postcard from Svante Arrhenius to Georg Bredig, January 1896

In 1896 Svante Arrhenius thanked Georg Bredig for sending him Liengnitzer Bomben. Liegnitzer Bomben, also known as Legnica bombs or legnickie bomby, are small cakes made out of gingerbread and filled with fruit and marzipan. They were made to be Christmas treats or souvenirs of visitors from other cities.

Von SKopp - Eigenes Werk, CC BY-SA 3.0

The bombs were first made by the Müller brothers in 1853, but there is a fable associated with the recipe. According to legend, the recipe was presented to a baker by a mountain spirit in a dream. The baker had dreamed of making a famous dessert for Legnica. The mountain spirit, Rübezahl, gave the recipe to the baker. As the baker read the recipe gnomes appeared and started baking the bombs. When the baker woke up the kitchen was filled with freshly baked bombs and the recipe was written down, signed by Liczyrzepa, the mountain spirit.

The recipe has been a coveted secret after World War II and was patented so that it could not be shared. It is kept at the Copper Museum in Legnica and until recently it was not public.

Below is the original recipe translated from Polish

Liegnitzer Bomben (Legnica bombs)

Cake:

500 g flour

400 g honey

250 g sugar

200 g apricot jam

150 g butter

125 g chopped almonds

50 g chopped lemon jelly in frosting

50 g chopped orange jelly in frosting

125 g raisins

2 tablespoons cocoa

1 teaspoon gingerbread spices

4 ml rum

4 eggs

1 packet baking powder

margarine for greasing

breadcrumbs for sprinkling

For the topping:

200 g of chocolate

Preparation:

Melt honey, fine sugar and butter while stirring, then leave to cool. Eggs with cocoa, almonds, gingerbread spice and rum. Mix it with baking powder, flour and add the cooled honey mixture to it, mix.

Mix the washed, dried raisins with finely chopped marzipan, orange jelly, lemon jelly and jam. Instead of apricot jam, you can also use 100 g of small, baked, candied pineapples for the filling.

Grease 12 bomb molds and sprinkle with breadcrumbs. Half-fill the dough, put the marzipan mass on it and cover with the rest of the dough. Bake in an oven preheated to 350 degrees for about 30 minutes. Melt the chocolate glaze and spread on the Legnica bombs.

Scientist Spotlight in the Bredig Archives: Robert Koch, German Microbiologist, Physician, and Nobel Prize Winner

In February 1901, Georg Bredig, a physical chemist working in the laboratory of Wilhelm Ostwald in Leipzig, Germany, sent a copy of his habilitation thesis “Anorganische Fermente” (Inorganic Ferments) to the eminent German microbiologist and physician, Robert Koch (1843-1910), which Koch later thanked him for. A habilitation is the procedure to achieve the rank of professor in many European countries, including in the German speaking lands of Bredig’s time.

Together with Louis Pasteur, Robert Koch is regarded as one of the founders of modern microbiology, particularly for his discovery of various causes of infectious diseases such as cholera, tuberculosis, and anthrax. For his work on tuberculosis, Koch received the Nobel Prize for Physiology or Medicine in 1905. To learn more about Robert Koch, you can read his biography and view a photographic reproduction of his portrait in the digital collections of the Science History Institute.

Ernst Cohen (1896-1944).

Born in the Netherlands on 7 March 1869, Ernst Julius Cohen was a Dutch Jewish chemist who was known for his work with allotropy of metals. Cohen worked under Svante Arrhenius (1859-1927), Henri Moissan (1852-1907), and Jacobus van 't Hoff (1852-1911).

Throughout his life, Cohen studied the allotropy of tin; his research areas included polymorphism of both elements and compounds, photographic chemistry, electrochemistry, pizeochemistry, and the history of science. He published more than 400 papers and numerous books.

In 1913, Cohen became a member of the Royal Netherlands Academy of Arts and Sciences. In 1926, Cohen was elected a Foreign Member of the Royal Society. In 1942, the Gestapo (Nazi secret police) decreed that all Dutch Jews must wear the yellow badge, known as Judenstern in German. The yellow badge differentiated Jews from non-Jews. Soon after the April 1942 decree, Cohen was arrested by Nazi police for non-compliance and forced to resign from the Royal Netherlands Academy of Arts and Sciences.

He was one of 1.1 million people (and more uncounted people) murdered in a gas chamber at Auschwitz concentration camp. He died 6 March 1944.

The Nobel Institute and the Nobel Prize

On January 2nd, 1896, Svante Arrhenius wrote a postcard to his dear friend Georg Bredig, telling him the latest news of the great Nobelian fortune. Arrhenius further says that this fortune, left by Alfred Bernhard Nobel, will be put in a fund to "be used to reward scientific work from around the world."

This fund became the Nobel prize, awarded for Physics, Chemistry, Physiology or Medicine, Literature and Peace. Below is an excerpt from Alfred Nobel’s will, which describes the Nobel prize and each of its categories.

“All of my remaining realisable assets are to be disbursed as follows: the capital, converted to safe securities by my executors, is to constitute a fund, the interest on which is to be distributed annually as prizes to those who, during the preceding year, have conferred the greatest benefit to humankind. The interest is to be divided into five equal parts and distributed as follows: one part to the person who made the most important discovery or invention in the field of physics; one part to the person who made the most important chemical discovery or improvement; one part to the person who made the most important discovery within the domain of physiology or medicine; one part to the person who, in the field of literature, produced the most outstanding work in an idealistic direction; and one part to the person who has done the most or best to advance fellowship among nations, the abolition or reduction of standing armies, and the establishment and promotion of peace congresses. The prizes for physics and chemistry are to be awarded by the Swedish Academy of Sciences; that for physiological or medical achievements by the Karolinska Institute in Stockholm; that for literature by the Academy in Stockholm; and that for champions of peace by a committee of five persons to be selected by the Norwegian Storting.”

The first Nobel Prize would not be awarded until 1901. In 1903 Arrhenius would be the third person to be awarded the Nobel Prize in Chemistry for his electrolytic theory of dissociation.

In March 1905, Arrhenius wrote to Bredig that the Nobel Institute for Physics and Chemistry would open on October 1st, 1905. While the Nobel Institute opened in October 1905, the actual building wouldn't open its doors until May 1906. Because of this, the Nobel Institute of Physics and Chemistry met at Svante Arrhenius’s home.

In this letter, he writes about his hopes and goals for physical building. He says that the building has three floors, the first will be the institute, the second will be meeting rooms for the committee members, and the third will be for assistants and servants.

In Letter from Svante Arrhenius to Georg Bredig, February 1905 , Arrhenius tells Bredig of the modest conditions that Meyerhoffen and Jacobus Henricus van 't Hoff (1852 – 1911) work in. he provides measurements of the rooms and even comments on the poor lighting. He uses this as an example of what he does not want at his new institution and says that his laboratory will be “significantly better.”

Arrhenius continues to write to Georg Bredig about the institute through his life. Check out the digital collections for more Arrhenius letters in the archive!

As we're working through cataloging much of our Max and Georg Bredig Collection we find gems like this!

This book is Kleine fabel für meine geige (1933). It has not been cataloged yet but will be soon! Check back for updates.

The archive bib record is found here, which has links to the finding aid and the EAD version. You can also head to our digital collections site to see everything we've digitized in this collection so far! Spanning the years 1891 to 1947, this collection consists of photographs, correspondence, and manuscript materials chronicling the life and career of prominent German-Jewish physical chemist Georg Bredig (1868-1944) and, to a lesser extent, his son Max.

I wish all books would come bound like tiny briefcases from now on.

The Othmer Library recently acquired the archival collection of Georg and Max Bredig, father and son German-Jewish chemists who immigrated to the United States as World War II was threatening their livelihood in Germany.

The archival collection included tons and tons of books and journals that have made their way into our modern collection, and we are just chuffed about it! Pictured above is Deutscher Kalender für Elektrotechniker. We are still in the process of cataloging this donation and will update this post later on with a link to it's record!

The Curse of Billy Penn

Did any of our followers know that there is a statue of William Penn on top of Philadelphia's City Hall?

We recently picked up a few new (to us) copies of Scientific American, a science and technology journal, from a local library (shout out to The Union League!). One issue features the statue of William Penn, founder of Pennsylvania (though it is important to note that Philadelphia specifically is the ancestral home of the Lenni Lenape or Lennapehoking people), before it was placed on top of Philadelphia City Hall.

William Penn was the product of Alexander Milne Calder, a Scottish-American sculptor, and is 37 feet tall.

For almost 90 years there was an unwritten agreement or understanding that forbade any building in the city from rising above William Penn. This agreement ended when Liberty Place was approved and built in 1987 causing the Curse of Billy Penn to cause disaster on all Philadelphia sports-teams. Pre-1987 Philadelphia sports teams enjoyed a run of success. Post-1987, the curse held on to the city so tightly until the Philadelphia Phillies won the World Series in 2008.

How did the curse end? Well it did and then didn't. The Comcast Center was built in 2007 and a few iron workers decided to place a tiny statue (about 4 inches tall) on top to make William Penn, yet again, the tallest figure in the city. The Philadelphia Phillies won the World Series in 2008, breaking the curse.

Then! In 2017, a new building became the tallest building in Philly. A second Comcast Center. Once again, iron workers placed a tiny Billy Penn on top... the Philadelphia Eagle went on to absolutely crush the New England Patriots in the 2018 Super Bowl. Go birds!

The Andrée's Arctic Balloon

Photo: Perspektivet Museum

In 1897, a group of Swedish explorers went to the North Pole in an air balloon and disappeared. Their fate would not be known for 30 more years. Tendrils of this story can be found in the letters between Svante Arrhenius and Georg Bredig.

The Andrée's Arctic balloon expedition took place in 1897 in which S. A. Andrée, Knut Frænkel, and Nils Strindberg voyaged by hydrogen balloon from Svalbard in July 1897, the plan was to fly over the north pole, as a way to advance Sweden's place in the race to the north pole.

Svante Arrhenius tells Georg Bredig about his friend Strindberg’s impending expedition in a letter written only months before the expedition.

“Strindberg is supposed to leave his bride and travel with Andrée to the North Pole with the 4th version of the Perpetuum mobile (they leave on May 17th).” - Letter from Svante Arrhenius to Georg Bredig, May 1899

On July 21, 1897, Arrhenius wrote

“One topic of lively discussion here is the polar expedition and how its three explorers are faring. The trip may take a month or maybe even longer. Perhaps they are sitting in snowdrifts and cannot travel further. Such a situation must be unpleasant.”

Letter from Svante Arrhenius to Georg Bredig

Andree was Sweden's first balloonist and proposed the expedition. Fraenkel was a Swedish engineer and Strindberg was a Swedish scientist and photographer. Unfortunately, the expedition was not completed and all three expedition members perished.

The balloon quickly lost hydrogen within the first two days of the expedition and crashed into a pack of ice, leaving the explorers in Svalbard. In October 1897 the three men made it to Kvitøya (White Island) in Svalbard. The island is almost completely covered in an ice cap and uninhabited. The three men were not able to survive the harsh arctic weather and perished.

Posing with the wreck (via Tekniska museet)

No one knew the fate of the explorers until August 5, 1930, when, due to a particularly warm summer, sealers could access the island. There they found the remains of the three men, their boat, journals, and exposed rolls of film that Stringbeg had taken. 93 photographs were able to be developed.

The photographs capture the balloon’s crash and the months following. The photographs show the camps they set up, hunting polar bears, and other realities of living in the arctic.
