In 1865 the Great Hall was enlarged by the architect David Bryce, who ordered the roundel portraits from George MacCallum. MacCallum was paid four pounds per profile, a total of £60 for the set of 15 ‘Heads with wreaths’.

The portraits appear along the frieze in the Great Hall. Each of the figures in the roundel portraits is surrounded by a laurel wreath which is both an aesthetic, decorative feature, and a classical symbol which emphasises the importance of the figure depicted in the portrait.

Arguably this profile offers a less complimentary depiction of Boerhaave than other portraits, such as the painting by (or after) Johan Wilhelm Kaiser. Perhaps particularly striking is the detailing of Boerhaave's nose.

Herman Boerhaave (1688 – 1738)

Boerhaave was one of the most famous medical thinkers of the early eighteenth century. He believed strongly in the significance of material facts in medical knowledge and emphasised the importance of experimentation and mechanical reasoning. Boerhaave was particularly important for his introduction of regular bedside visiting and diagnosis. These clinical practices, which he taught at Leiden, were subsequently taught at other universities including Edinburgh, Vienna and Pavia.
