Dry Storeroom No. 1


I recently read Dry Storeroom No. 1 by Richard Fortey. A strange title, but the subtitle tells you what it is about – The Secret Life of the Natural History Museum. The Natural History Museum in question is the one in London. This museum has been busy collecting stuff since 1753, when it was part of the venerable British Museum. It outgrew its “mother institution” and went off on its own in 1883.

I love old museums, so the only thing better than a book about an old museum would be one that brings you behind the scenes. Fortey narrates a fun trip through the offices and labs of quirky scientists, and storerooms full of dried, pickled and fossilized specimens from around the world. The only thing drier than the mounted insects is Fortey’s sense of humor, which I suppose is a requirement for someone who spent his working life in this museum studying trilobites.

One of the primary missions of any natural history museum is taxonomy, that is, helping to name the millions of extant and extinct species of animals, vegetables and minerals here on earth and in the cosmos. Naming things might not seem like the most interesting part of science, but it is the critical first step to studying and understanding nature. Tens of thousands of new species are discovered every year. Many of these are now identified through “shotgun sequencing” of the DNA of millions of microbes scooped up in soil or seawater, but many new insects and even larger animals are still discovered. Discovering and naming something new, no matter how small its physical dimensions, is always exciting.

Having worked at the Natural History Museum for 35 years, Fortey saw many changes in museum life. One of the biggest was surely technology. Scientists have moved from a reliance on the visible differences between species (“counting hairs on legs” as he puts it), to an analysis of the differences between their DNA. Giving names to new species now seems like an antiquated formality – what matters is the species’ “DNA barcode”. This is published along with the physical description, so that other researchers can compare the DNA sequence of an unknown species to the database of barcodes to make an identification.

Fortey prefers to be “Sepia Man with his microscope and library” rather than “Barcode Man with his primers and his white coat”, but he acknowledges that both are needed. One change where he does not see an upside is the decreasing support for basic research. Preference is given to new projects and grant proposals with known practical applications. The future applications of basic research may be unknown, but often turn out to be just as practical.

Fortey tells the story of one researcher at the museum who was a cryptogamist – a specialist in cryptogams. Cryptogam comes from the Greek for “hidden marriage”, and it refers to plants that reproduce via spores (whose function was “hidden” from scientists until they discovered it under the microscope). This man devoted his life to studying seaweed, a type of cryptogam.

When World War II broke out, the draft board assigned the museum’s specialist in cryptogams to the intelligence agency responsible for decoding Nazi cryptograms. Although only one letter different, cryptogram is from the Greek for “hidden writing”. So the seaweed expert was assigned to break codes.

Fortunately, the importance of basic research was proven again, when a captured German U-boat was found to contain vital code books. Although our hero didn’t know much about breaking codes, he knew a lot about preserving organic matter that has been pulled from the sea. The rescued code books helped break a highly secure version of the Enigma Code being used by the U-boat fleet, allowing Allied supply ships to avoid torpedo attacks and ensuring victory in the Battle of the Atlantic.

Galileo's Tomb


Welcome back to Kind of Curious! I hate to say, but it’s been almost a year since I last posted. So I have quite a backlog of curious things to write about.

One of the things I did during 2011 was to visit Italy with my wife. This was the first time either of us had been to Europe, so we were completely in awe of this entirely different environment and way of life. Of course we knew that a whole “old world” was out there, which had brought both of our families to the new world. But until we experienced it ourselves, no book or movie could explain it to us (although maybe a blog could) …

A great place to begin describing the wonderful things we saw in Italy is Santa Croce Basilica in Florence. There seems to be a church on every street corner in Italy (sometimes 3 or 4 on a corner), each with priceless art or religious relics of the kind that in the US can only be found in museums.

What is unique about Santa Croce is that it has become a monument to the famous sons and daughters of Italy. Because of this, it is sometimes called the “Pantheon of Italian Glories” (“pantheon” being Greek for “temple of the gods”). That’s sort of a sacrilegious nickname for a church, but not the only inconsistent thing going on here as you will see.


A church has been at this site since 1210. The caption for the above drawing on Santa Croce’s website begins “around 1252 it was felt necessary to construct a church that was larger…”. I would have to agree with that. The priests look a little worried about where the congregation is going to sit.

The present church began construction in 1294 and was mostly completed by 1442. We get excited in the US when we see something from the 1700’s! The marble façade that gives the church the look it has today was not completed until 1863. Who in the US would embark on a construction project that would take over 500 years to complete?

Santa Croce’s journey to become the “Pantheon of Italian Glories” began in 1570, when they decided to build a tomb for Renaissance artist Michelangelo, who lived much of his life in Florence.


Since that time they have added many more tombs of the rich and famous, including that of the “father of modern science” Galileo, which was completed in 1737. Renaissance author Machiavelli is also buried here. If you deceive and manipulate others for your personal gain you are “Machiavellian”, like the advice given to the title character in Machiavelli’s book The Prince.


Galileo’s tomb is shown at the beginning of this post. It is ironic that Galileo is buried here, considering his rocky relationship with the Catholic church. Galileo was placed under house arrest by the Inquisition in 1633 for his support of Copernicus’ heretical observation that the earth revolved around the sun (rather than the earth being the center of the universe as described in the bible). Galileo died in 1642.

The church allowed some of Galileo’s works to be reprinted in 1718, which would explain why a monument in his honor would be allowed in Santa Croce in 1737. But his book that was at the center of this controversy, Dialogue Concerning the Two Chief World Systems, was not allowed to be reprinted in its uncensored version until 1835. And it wasn’t until 1992 that Pope John Paul II finally admitted that the church had made a mistake in condemning Galileo!

Incidentally, Machiavelli’s book The Prince was also banned by the Catholic church. But this was not until after his death, and he was not accused of heresy. Although his Machiavellian ideas do not seem Christ-like, the book was actually banned because French leaders who were following its advice were being accused of corruption.

Here is the exterior of the church. Note that the marble is only on the front. There was no word as to whether they are planning on finishing the sides and back with marble as well. Give them time, it’s only been 700 years. And note the blue Star of David just below the peak of the top roof. The architect for the façade was Jewish, and in an inspiring act of interfaith cooperation was allowed to include the Star of David. He is even buried on the church grounds.
