A MAXWELL CHAIR
This chair is from Aunt Jane Cay's home at 6 Great Stuart Street, Edinburgh. It is on permanent loan from James Brown, a descendant of the Cay family. It is embroidered in cross-stitch by Jane Cay to illustrate the wave theory of light. James Clerk Maxwell would sit in this chair to do his homework when staying with his aunt as a schoolboy at the Edinburgh Academy.
AUNT JANE'S DRAWING ROOM
The two watercolours showing the drawing room of Aunt Jane Cay's house are by her. They feature, respectively, Jane Cay herself seated in the chair described above, and James Clerk Maxwell as a schoolboy at the tea-table. The former watercolour is a gift from David S. Ritchie (Trustee) and the latter is on permanent loan from James Brown (see above.)
WATER COLOURS BY JEMIMA WEDDERBURN
Maxwell's first cousin, Jemima Blackburn, née Wedderburn, eight years older than he, demonstrated a precocious talent for drawing and painting. She drew in water colours nearly every day, maintaining a visual diary of incidents going on around her. Not much escaped her eye, that of a born diarist and artist, and her young cousin James came to be included frequently in the family groups that she delighted to portray. The early years of his life were those in which the cousins were most frequently together, and consequently we have in her work good representations of family events, showing Maxwell as a small boy, usually in the presence of his father. Many of these sketches of unique biographical interest are now in the possession of the Foundation and are on display in the house. They are:
A family play featuring JCM and Wedderburn children.
A family party featuring JCM and Wedderburn children.
JCM with his father at the Highland Cattle Show.
JCM and Jemima paddling in washing tubs on the River Urr.
Jemima and her mother being led on horseback by JCM and his father at Glenlair.
The Wedderburns arrive at Glenlair by at night.
JCM and his father at Newton en route to Glenlair.
JCM and his father arriving by horse-drawn coach at 31 Heriot Row, Edinburgh, to stay with the Wedderburns.
JCM and his father awaiting the arrival of the early steamship at Granton Pier.
Family picnic on the shore at Roshven, Lochailort, home of the Blackburns. JCM as an adult while at Marischal College, Aberdeen.
The Foundation also possesses an album of watercolours by Jemima, depicting her journeys in Italy.
THE STAIRWAY GALLERY OF ILLUSTRISSIMI
Another highlight on display is the Stairway Gallery of Illustrissimi: framed engraved portraits of illustrious mathematicians and physicists arranged in chronological order as one ascends the two flights of stairs. Many of these engravings are from the personal collection of Sir John Herschel (1792-1871), which was sold at a Sotheby auction, 3-4 March 1958. Undeniably, because of this source, there is a pro-British bias to the selection of great names.
