| Interesting
aspects concerning Southern African Astronomers |
|
This
page is about outstanding astronomical achievements and discoveries made
by Southern African Astronomers. Also listed are distinguished recognition
received for Astronomical work, whether it is the election to a society
/ medals received, etc.
Furthermore Southern African Astronomers are also interesting people
and do interesting things outside the subject of Astronomy. They not only
talk about stars are / were dynamic persons who also partake in a variety
of other activities:

Academically:
- Childe
was appointed in 1845 as second assistant at the Cape
Observatory.
He resigned in 1852 to become Professor of Mathematics at the
South African College. (Later renamed the University of Cape Town.)
- Due
to the addition of the Magnetic Observatory to the Cape
Observatory
Smalley was appointed as third assistant, but he resigned in
October 1851 to become Professor of Mathematics at the South
African College (S.A. College later became the University of Cape
Town.)
- Evans

Wranglers at University:
'Wrangler is the name given in the University of Cambridge to those
who have attained the first class in the public mathematical honours
examination. The word itself is derived from the public disputations
in which candidates for degrees were, in former times, required to
exhibit their powers.'
Fallows
wasThird Wrangler at Cambridge in 1813.
Finlay
was 33rd Wrangler.
Herschel
was Senior (1st) Wrangler at Cambridge.
Stone

Art:
A
few astronomers turned out to be great artist:
Thomas Bowler
Bowler
came out to South Africa (1834) from the United Kingdom as footman to
Thomas Maclear.
He was taught to be handy around the Cape
Observatory,
and Maclear went on to employ Bowler as an assistant. After working
for the Observatory for a year he was dismissed by Maclear for insolence.
Bowler then found employment "in a gentleman's family to teach the children
drawing and the use of globes …"
Bowler went on to become one of the most important artists in the Cape
Colony. He made twenty or more paintings of the Cape Observatory, and
much of what we know of how the terrain looked at the time was due to
him.
Charles Piazzi Smyth
Smyth
was Assistant director to Maclear,
and was later to become Astronomer Royal for Scotland. He was
also an excellent artist and much of our visual knowledge of the Arc
of the Meridian
project comes from his paintings
and caricature sketches.
William Mann
Mann
was Second Assistant to Maclear.
He was colour blind but was none the less a great artist. Mann and Smith
both worked together at the Cape Observatory and were friends.

Discoveries
and Achievements in the field of Astronomy
- Cousins did
photoelectric photometry, establishing UBV stellar standards
in the E region of the southern celestial hemisphere.
- Evans
co-discovered the Barnes-Evans relation which connects the
surface brightness of a star to its V-R colour. This enables
the radii and distances of Cepheid pulsating variables to be determined
from light, colour and radial velocity measurements around their pulsation
cycles.
- Finlay
discovered the "Great comet of 1882". (C/1882R1)
- Finsen
developed the Finsen
Eyepiece Interferometer.
He discovered 73 double stars and took 54 000 photographs
of Mars. These were considered to be the best photographs
of Mars until the space probes became available.
- Gill
designed the Reversible
Transit Circle.
- Henderson
measured the first stellar distance by parallax method to Alpha Centauri.
- Herschel
set up a catalogue of double stars, nebulae and clusters of
the Southern Sky
- Hertzsprung
independently from Henry Norris Russel, around 1913, had
first put forward the idea that later became known as the Hertzsprung
Russel Diagram.
- Innes
discovered Proxima Centauri, faint companion star to Alpha
Centauri, in 1912.
- Jackson
Cyril discovered
/ co-discovered three comets and 72 asteroids.
- Jackson
John
measured the stellar parallax of 1 600 southern stars with greatly
improved accuracy.
- Lacaille
laid the foundations for Southern Hemisphere Astronomy with his star
map (with 10 000 measured positions) and the creation of new constellations.
He also did ground breaking Land Survey work with his measurement
of the Arc
of the Meridian.
- Maclear
for re-Measuring the Arc
of the Meridian.
- Nevill
published the first book on the Moon in English in 1876.
- Roberts
AW
made 250 000 measurements of 98 variable stars during 1891
to 1920.
- Rossiter
published the "Catalogue of Southern Double Stars"
in 1955. He made 5 534 discoveries of double stars and 23 814
measurements.
- Smythe
was only 17 years old when he was appointed assistant astronomer
at the Cape
Observatory.
He was recognised as a leading spectroscopist.
- Spencer-Jones
was Chairman of Commission 34 of the International Astronomical Union
tasked with observing the closest approach of minor planet Eros
in 1930.
- Stoy
did meticulous groundbreaking work to establish photometric standards
in order to determine the true colours and brightness of stars.
- Stone
was appointed as the directing astronomer for the British Transit
committee for the 1882 Transit
of Venus.
He also produced the Catalogue of Southern Hemisphere Stars
and the Radcliffe Catalogue.
- Van
der Bos
discovered a record amount of double stars and published
a catalogue of double stars which was the standard for the
time.
- Wood
was a famous comet, asteroid and minor planer hunter.
- Zanstra's
work became known as the Method of Nebular Astrophysics.

Photography:
Very
important pioneering work was made in the field of photography.
David Gill
Gill
is considered as the pioneer of Astrophotography. In 1869 he took a
photo of the Moon, one of the 1st persons ever to do so. His
big breakthrough in Astrophotography came much later when in 1882 he
took a photo of the "Great Comet". The background showed stars
very clearly and Gill realised that photography can be used as a tool
to study stars. Due to his pioneering work a photographic survey of
the sky named the Cape
Photographic Durchmusterung
was initiated. Later the Paris Observatory was interested in creating its
own map of the sky, and enlisted the help of Gill. This project was
known as Carte
du Ciel.
John Herschel
Herschel
was a pioneer of photography. He first described the use of sensitive
paper, and used "hypo", or hypo sulphite of soda, as a fixing
agent. Herschel first used the terms 'positive' and 'negative',
and he may have coined the term 'photography' (under dispute).
Herschel took a series of photographs at the Cape with his camera
Lucinda, and this forms a very useful record of Cape Town,
Cape
Observatory
and his own Observatory called Feldhausen.
Charles Piazzi Smyth
He was in correspondence with Herschel.
Smyth's collotypes provide the earliest extant photographic illustrations
of Cape scenes. They are kept at the Royal Greenwich Observatory,
and at the Royal Society of Edinburgh. Smyth also published the
first book with stereoscopic pictures and constructed a remarkable
miniature camera.
