Gretchen Anderson retires from Carnegie Museum of Natural History
They finally let me leave, lol

Hello Gretchen, I hope
you are well. Is it true that after 16+ years you retired as conservator at the
Carnegie Museum of Natural History (CMNH)?
It is true, almost a year ago now. They finally let me leave, lol. But I left them in good hands. We hired a very talented conservator from Switzerland, Annick Vuissov. She has a very broad experience, including working on conservation projects in all parts of the world, including Antarctica, where she preserved the Shackleton huts. She is a good fit for CMNH.
What are some of your
proudest accomplishments in your time at CMNH?
That is a big question - it is hard to say - there were so many projects that I am very proud of. One of the accomplishments that I am most proud of is developing and strengthening relationships across not only the natural history museum, but across all 4 Carnegie museums. The CMNH is one of 4 sister museums under the Carnegie name: Carnegie Museum of Art (with whom Natural History shares the original 1897 building), the Andy Warhol Museum, and the Science Center. I helped to improve synergy between all 4 institutions, sharing conservation equipment and collection management knowledge. I also developed very strong relationships with our facilities department (shared by all 4 institutions), significantly improving environmental conditions for Natural History through a better understanding of what conservation could do. Within Natural History, I improved collaboration with the various science (collection) departments, building relationships with collection managers and curators for improved overall collection care. I strengthened collaboration between conservation, collections, and the exhibits departments, by helping to show how conservation could aid each of those areas.
These collaborations resulted in a major exhibition opened in 2024 called Stories We Keep: Conserving Objects from Ancient Egypt. (https://carnegiemnh.org/explore/stories-we-keep/) The goal of the exhibition was multi-layered and grew out of the need for a large conservation space to work with the updating of many of the traditional galleries. The first gallery to be renovated was the Egyptian Gallery, with its centerpiece of a 30-foot-long funerary boat from the 12th Dynasty (1991-1802 BCE). We created a conservation visible lab to treat the 800 + objects (including the boat) that were on display. The visible lab is the central element of the exhibition, which focuses on why we humans collect things and how we manage to preserve them. This exhibition is a collaboration between the CMNH Exhibition department and Conservation, with the visible lab being my idea. This exhibit has been so successful that the lab has now been expanded, and the exhibit has been expanded to focus on how we collect through the scientific perspective.

This exhibition demonstrates the culmination of what I wanted to do for the past 16 years at CMNH.
Other projects that I am proud of:
• Collaboration with CMNH Collection Manager for the Bird Collection on reducing natural light levels in her storage area and in developing safer methods for storing the large egg collection and historic taxidermy. The light level reduction was done by demonstrating a cost-effective way to approach this serious problem, with full administrative support. We leveraged the support through federal grants that enabled purchase of better (conservation grade and more space efficient) cabinets.
• Collaboration with the Amphibian and Reptiles Curator to significantly improve and expand storage capacity for the fluid collection (specimens stored in alcohol) through a joint grant proposal (NSF Grant). The fluid collections at CMNH are stored in a purpose-built structure built in 1907 and is on the national historic registry. It is gorgeous. While our grant did not solve all the problems (the biggest being being the lack of environmental control), it did create a significant amount of additional space to manage the collection.
• Improvements in Integrated Pest Management (IPM) across Natural History, Art and the Andy Warhol museum (AWM). I convinced our facilities department to hire a single pest management company to manage all 4 institutions, and to allow me to work directly with the technician so that he understood our goals. I worked with the conservator in the Art Museum, to mitigate several moth infestations and develop a strategy to reduce recurrences. I collaborated with the senior registrar at AWM to address a serious infestation in their collection. We worked together on a solution that included extensive monitoring, treatment, and documentation. We were able to reduce the infestation significantly. It was an interesting challenge with a very successful conclusion. A white paper on the challenge was written and is located on MuseumPest.Net (https://museumpests.net/wp-content/uploads/2014/04/1-2-Morgan-and-Jacobs-paper.pdf). Finally, I worked closely with Natural History collection managers to improve and standardize their isolation protocols and treatments, improving housecleaning in the process.
• Successfully mitigated 8 water emergencies. The historic building that holds Natural History and Art is old and is on the national registry. It was originally constructed in 1895, with additions in 1895, 1907 and 2005. It is a complicated building, with some very old infrastructure. In my 16 years there were several failures - to the roof, to plumbing, and to drainage pipes. In all of these emergencies, I worked closely with the facilities department to not only mitigate the floods, but to to plan for repairs to the building and the infrastructure to reduce the risk.
• Conducted a major General Conservation Assessment to develop priorities for improving collection care.
• Conducted an environmental survey that identified weaknesses in the environmental conditions and informed plans for improvements.
• Conducted a Risk Assessment for collection care.
What have you been
doing with all your
FREE time the last year?
HAHA! What free time!! To begin with, the museum hired me back to work with a small local museum (The Latin American Cultural Center of the Latin American Studies Association (LASA) to conserve the objects and specimens borrowed from CMNH for the exhibit: Costa Rica: Between Oceans and Continents (https://costarica.lasaweb.org/en/). The museum’s new conservator (Annick) and her team were busy working on the second phase of the Stories We Keep series, so I was hired to work on the 30 archaeological objects and a half dozen historic taxidermy specimens, some of which needed significant intervention. This kept me very busy and very happy. It was a pleasure to work with these wonderful pieces, mostly dating to the first half of the 20th Century, from a time when taxidermy was truly an art form. Treatments ranged from simple cleaning (they needed it desperately) to repairs on both the specimens and the naturalistic mounts.
Moving home to Minnesota:
On top of that, my husband and I had already decided to move back to Minnesota, where we grew up. He had a family emergency that demanded he move back to Minnesota, and that kept him busy. He looked for a new home (and found it) while I prepared our Pittsburgh house for sale, including packing for the move. Everything worked out - we sold our house, bought a new one and barely survived a move from hell. Needless to say, I was exhausted and just beginning to recover in time to start teaching again!
Oh, is that all. Now that you have moved back to Minnesota are you going to kick back and live a life of leisure?
Hardly! I am teaching five online professional development courses this year for Museum Study beginning with Keeping Historic Houses & Museums Clean in March, Introduction to Integrated Pest Management in April, Storage Techniques in June, Integrated Pest Management: The Plan & Implementation in August, and Materials for Exhibit, Moving, and Storage in November
There will be some leisure activities, beginning with adopting a dog (we have been without since moving to Pittsburgh). I will also be gardening - landscaping my new beautiful yard- and listening to music (my husband is a professional musician and is getting back into the Minneapolis music scene).
What new things are
you planning to do?
When I get my new home in order and my office set up, I plan to make myself available for consulting for conservation projects. I have spent the past 40 years developing and learning preventive conservation techniques and am eager to share my knowledge and expertise through workshops and as a consultant. I would also like to get involved with some local museums, including the Science Museum of Minnesota where I spent the first 30 years of my professional life. (conservation career)
Whew, I’m worn out
just hearing about the last year. Thank you for sharing what you have been up
to. We look forward to seeing what you get up to next.
