* A Gullstrand, Speech at the Nobel Banquet in Stockholm, December 10, 1911

Sir Isaac Newton was probably the discoverer of astigmation ; the position of the astigmatic image lines was determined by Thomas Young ( A Course of Lectures on Natural Philosophy, 1807 ); and the theory was developed by Allvar Gullstrand.

Allvar Gullstrand ( 5 June 1862, – 28 July 1930 ) was a Swedish ophthalmologist.

Born at Landskrona, Sweden, Gullstrand was professor ( 1894 – 1927 ) successively of eye therapy and of optics at the University of Uppsala.

Though the slit lamp is a combination of these two developments, the first concept of the slit lamp dates back to 1911 credited to Alvar Gullstrand and his “ large reflection-free ophthalmoscope .” The instrument was manufactured by the company Zeiss and consisted of a special illuminator that was connected by a small stand base through a vertical adjustable column.

When changing to a different coordinate system ( for example Lemaitre coordinates, Eddington-Finkelstein coordinates, Kruskal-Szekeres coordinates, Novikov coordinates, or Gullstrand – Painlevé coordinates ) the metric becomes regular at r = r < sub > s </ sub > and can extend the external patch to values of r smaller than r < sub > s </ sub >.

The unsymmetrical form of the meridional pencil — formerly the only one considered — is coma in the narrower sense only ; other errors of coma have been treated by Arthur König and Moritz von Rohr, and later by Allvar Gullstrand.

* June 5 – Allvar Gullstrand, Swedish ophthalmologist, winner of the Nobel Prize in Physiology or Medicine ( d. 1930 )

* July 28 – Allvar Gullstrand, Swedish ophthalmologist, recipient of the Nobel Prize in Physiology or Medicine ( b. 1862 )

* Allvar Gullstrand ( Sweden ), Nobel Prize winner in 1911 for his research on the eye as a light-refracting apparatus.

Gullstrand is noted also for his research on astigmatism and for improving the ophthalmoscope and corrective lenses for use after removal of a cataract from the eye.

In 1921, Painlevé proposed the Gullstrand – Painlevé coordinates for the Schwarzschild metric.

He is the only one to mention Allvar Gullstrand.

It wasn ’ t until 1919 that several improvements were made to the Gullstrand slit lamp made by Vogt Henker.

To the north-northwest is the smaller Gullstrand.

Gullstrand is a lunar impact crater that lies on the northern hemisphere on the Moon's far side.

A small, bell-shaped crater forms a break through the rim to the southwest, and a small craterlet is attached to the southeastern side along the rim of Gullstrand.

There are also tiny craters along the rim of Gullstrand along the northern and southern edges.

The inner walls of Gullstrand are relatively simple and featureless, and the interior floor is not marked by any craters of note.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Gullstrand.

Other notable metrics are Eddington – Finkelstein coordinates, Friedmann – Lemaître – Robertson – Walker metric, Gullstrand – Painlevé coordinates, Isotropic coordinates, Kerr metric, Kerr – Newman metric, Kruskal – Szekeres coordinates, Lemaitre metric, Reissner – Nordström metric, Rindler coordinates.
