Whether you love L. S. Lowry, Lucian Freud or Richard Long, you know that when you visit Amgueddfa Cymru – National Museum Wales you can always see outstanding examples of international modern and contemporary art. What you might not know is that a significant part of that collection is here thanks to The Derek Williams Trust, which lends Amgueddfa Cymru over 260 of its most important works of twentieth and twenty-first century art.

This week sees the launch of The Derek Williams Trust website, a fantastic resource for anyone interested in exploring this collection. The site will enable you to search for art works and artists, and discover more about the Trust and its work with Amgueddfa Cymru.

Derek Williams was a Cardiff-based chartered surveyor and art lover, who had a particular interest in mid-twentieth century British art. He collected a large number of works by John Piper and Ceri Richards, which were supported with works by major figures such as Ben Nicholson, Henry Moore, David Jones, Ivon Hitchens and Josef Herman. Following Williams’ death in 1984, his collection and the residue of his estate were left in trust. Since that time, The Derek Williams Trust has undertaken the care, enhancement and public display of the collection, and in turn lends the collection to Amgueddfa Cymru – National Museum Wales. The generous support of Trust has transformed the Museum’s collection of twentieth century art and parallels the great bequests of French Impressionist art made by Gwendoline and Margaret Davies a generation earlier.

Since 1992, The Derek Williams Trust has also been working with Amgueddfa Cymru to build its own collection of modern and contemporary art, and recent purchases include work by Howard Hodgkin, George Shaw, Anthony Caro and Clare Woods. The Trust also provides financial support for Museum purchases, and funds the biennial Artes Mundi Derek Williams Trust Purchase Award – recent recipients include Tanja Bruguera, Ragnar Kjartansson and Bedwyr Williams.

The first dinosaur footprints found anywhere in Europe

One sunny evening in September 1878, Welsh artist and naturalist Thomas Henry Thomas was wandering around the small village of Nottage, just outside Porthcawl. The rays of the setting sun were shining across a large slab of rock placed on the edge of the churchyard. The local villagers told him that the five strange markings on the rock were the footprints of the devil as he strode across the slab. The rock had lain between the church and the village pub for years, and was a local curiosity.

Thomas was a well-educated man, born in Pontypool in 1839, and had studied Art at the Royal Academy, before returning to Wales. He was a key member of the Cardiff Naturalists Society, and a well-respected artist as well. On discovering the footprints, illuminated by the setting sun in the churchyard, he was struck by the similarity between these markings and newly found dinosaur footprints in North America. He quickly sketched the prints and informed various local geologists. John Storrie, curator of the Cardiff Museum, visited the site and made a cast of the trackway.

The President of the Cardiff Naturalists Society was Colonel Turbervill, who arranged for the rock to be brought to the Cardiff Museum for safe-keeping.

Thomas H. Thomas wrote a short paper, in January 1879, describing the footprints and also his attempts at Bristol Zoo, to persuade a suspicious Emu to walk across modelling clay, for comparison! He described the footprints as "Tridactyl Uniserial Ichnolites", but left it to Professor W Sollas of Bristol University to publish a formal description, with the name Brontozoum thomasi. We now know that these footprints were made 220 million years ago by a medium-sized meat-eating dinosaur, similar to Megalosaurus which evolved later.

The original footprint slab was around 6' 6" long and 5' 6" wide, and about 6 inches thick, although excess rock was later removed to make it easier to handle and display. When the collections of the old Cardiff Museum were transferred to the new National Museum of Wales in 1907, the footprints were one of its most important acquisitions. Currently the fossil is on display in the

, as befitting the first dinosaur footprints found anywhere in Europe.

Wales has an important place in the evolutionary history of dinosaurs; not only this early set of footprints, but also another major trackway site near the town of Barry, which is one of the most significant sites of its age in Europe. The rocks of this area were laid down around 220 million years ago, at a time when Wales was a low-lying desert, similar to those in the Arabian Gulf today, and dinosaurs had just evolved. Over the next 20 million years, the sea-level rose and the deserts disappeared underwater. However the dinosaurs living on higher ground continued to diversify into different species, one of which was Dracoraptor, the small theropod dinosaur found near to Penarth in 2014, and now on display at the National Museum Cardiff.

Mae Amgueddfa Cymru wedi derbyn rhodd anhygoel gan y ffotograffydd Magnum, David Hurn. Mae Hurn yn un o ffotograffwyr dogfennol mwyaf dylanwadol Prydain. Ac yntau bellach yn byw ac yn gweithio yma yng Nghymru, mae wedi dychwelyd at ei wreiddiau Cymreig – ac yma y bydd ei gasgliad o ffotograffau’n aros diolch i’w rodd hael.

Mae’r casgliad yn rhannu’n ddwy ran, sef tua 1,500 o’i ffotograffau ef ei hun sy’n cwmpasu ei yrfa o dros drigain mlynedd fel ffotograffydd dogfennol; a thua 700 o ffotograffau gan ffotograffwyr eraill o’i gasgliad preifat. Wrth sôn am ei rodd, dywedodd Hurn:

“Fy atgofion gweledol/diwylliannol cynharaf yw ymweld â’r Amgueddfa pan oeddwn i’n bedair neu’n bump oed. Dwi’n cofio’r cerflun drwg – y Gusan gan Rodin – a chasys yn llawn stwff oedd pobl wedi ei roi. Wel, bellach mae gen i gyfle i dalu rhywbeth yn ôl – bydd rhywbeth gen i yno am byth. Mae’n fraint o’r mwyaf.”

Detholiad Diffiniol o Waith Oes

Dros y ddwy flynedd ddiwethaf, mae David wedi bod yn dewis ffotograffau o’i archif ef ei hun sy’n ddetholiad o waith ei oes. Mae’r casgliad o tua 1,500 o brintiau newydd yn cynnwys gwaith a wnaed yng Nghymru, Lloegr, yr Alban, Iwerddon, Arizona, Califfornia ac Efrog Newydd.

Mae’n cynnwys rhai o’i ffotograffau enwocaf, fel Dawns y Frenhines Charlotte, Barbarella a Grosvenor Square.

Fodd bynnag, ei ffotograffau craff a gofalus o Gymru yw prif ffocws y casgliad. Yn dilyn rhodd hael David, Amgueddfa Cymru yw ceidwad y casgliad mwyaf o’i luniau yn y byd.

Casgliad Cyfnewid

Drwy gydol ei yrfa hir, mae Hurn wedi bod yn cyfnewid llun am lun â’i gyd-ffotograffwyr, llawer ohonynt yn gydweithwyr iddo yng nghwmni Magnum.

Mae’r casgliad pwysig ac amrywiol hwn o tua 700 ffotograff, sydd hefyd yn dod i law’r Amgueddfa, yn cynnwys gweithiau gan ffotograffwyr blaenllaw’r 20^fed a’r 21^ain ganrif.

Yn eu mysg mae Henri Cartier-Bresson, Eve Arnold, Sergio Larrain, Bill Brandt, Martine Franck, Bruce Davidson a Martin Parr, Bieke Depoorter, Clementine Schneidermann a Diana Markosian. Henri Cartier-Bresson, Eve Arnold, Sergio Larrain, Bill Brandt, Martine Franck, Bruce Davidson a Martin Parr, a ffotograffwyr sy’n dod yn amlycach megis Bieke Depoorter, Clementine Schneidermann a Diana Markosian.

Bydd detholiad o ffotograffau o gasgliad preifat David yn cael eu harddangos am y tro cyntaf yn Amgueddfa Genedlaethol Caerdydd o 30 Medi 2017 ymlaen. Bydd Llun am Lun: Ffotograffau o Gasgliad David Hurn yn lansio oriel ffotograffiaeth newydd yr Amgueddfa.

Casgliadau Ffotograffig yn Amgueddfa Cymru

Mae casgliadau ffotograffau Amgueddfa Cymru’n unigryw am eu bod yn cwmpasu cynifer o feysydd a phynciau, gan gynnwys celf, hanes cymdeithasol a diwydiannol a’r gwyddorau naturiol.

Mae hefyd yn cynnwys ffotograffau pwysig iawn, fel rhai o’r ffotograffau cynharaf i gael eu tynnu yng Nghymru gan y ffotograffydd arloesol John Dillwyn Llewelyn a’i deulu. Bydd rhodd David yn gweddnewid casgliadau ffotograffiaeth yr Amgueddfa ac yn creu cyfleoedd cyffrous i ehangu’r casgliadau mewn ffyrdd newydd.

Bydd yr arddangosfa yn Amgueddfa Genedlaethol Caerdydd yn dilyn cyflwyniad o waith David Hurn yn Photo London, y digwyddiad ffotograffiaeth rhyngwladol a gynhelir bob blwyddyn yn Somerset House, Llundain. Wedi’i churadu gan Martin Parr a David Hurn, mae arddangosfa Photo London, David Hurn’s Swaps, yn dathlu pen-blwydd Magnum Photos yn 70 oed.

For the Royal Horticultural Society’s Flower Show in Cardiff this year, we decided to build on previous experience of creating real botanical windows. We wanted something that would form an eye-catching backdrop to the collections on display within Amgueddfa Cymru's woodland-themed marquee.

The botanical windows began in 2015 with our Museum in a House exhibit for the Made in Roath festival. We wanted a display that would reflect aspects of our Museum work as well as to represent the herbarium itself. We pressed plants following the standard method for creating herbarium specimens as shown below. In this way, plant specimens last for hundreds of years on conservation grade card and out of light in herbarium cupboards.

Method for pressing plants for long-term storage in the botany collections:

1. Select a plant showing as many characters as possible – fruit, flowers, roots.
2. Place between blotting paper, arranging the plant at the same time, to limit the amount of overlapping material.
3. Place in a plant press and tie as tightly as possible.
4. Place in a drier between 20 and 30^oC.
5. Change the blotting paper initially every day, and then less often until the plants are completely dry. This will take about a week.
6. Attach plant to conservation-grade card (for example made from cotton) using small strips of adhesive cotton tape. Place the tape strips strategically on the plant’s stems and leaves to hold it safely on the card. This technique allows for some flexing of the card without damage to the plant and for easy removal of the plant from the card for study.
7. Store out of light in an environment with humidity between 40 and 60 RH.

After pressing, we attached the plants to large sheets of tracing paper using small pieces of transparent tape strips (rather than the conservation grade materials we would normally use for the botany collections). The tracing paper was then wrapped carefully for transport to the site of the exhibit and then taped to sunny windows in the living room.

For the RHS Flower Show in 2016, we built on the initial idea but had the added complication of having to create our own windows to install in the marquee. We had nine 80 x 60 cm sheets of 2mm thick acrylic cut, with holes drilled into each of the corners for hanging. We attached the plants to these sheets using small transparent tape strips. Once at the Flower Show, we attached strong metal rings to the corner of each panel and hung the panels from the cross bars of the marquee by looping fishing line (the type strong enough to catch a 60lb fish!) through the metal rings. The only worry now was whether the ranges of temperature and humidity in the marquee would be too much for the transparent tape and we would arrive the next day to find the plants on the floor! We certainly would never subject pressed specimens from the collection to this environment. We were relieved to find that the panels held well the whole weekend – and with much praise from visitors.

In 2017, we planned to recreate the botanical windows for the Flower Show, but with a slight twist. We had a woodland theme, so we chose Welsh trees for each panel: Oak, Beech, Hazel, Hawthorn, Holly, Scots Pine, Yew and Lime. To make the display really stand out, we printed a silhouette of the tree with its Welsh, English and scientific name onto transparent material for the backdrop. We taped the transparencies onto the acrylic and then taped the pressed plants onto the transparencies as before. Unfortunately, this year was particularly warm weather – the transparent tape holding the pressed plants did not last as long on some of the panels, so remedial work had to be carried out to keep the display looking good.
