Conference Announcement:
------------------------ 

Sixth Annual Convention of the Antique Telescope Society
at Mt. Wilson Observatory, Sept. 12-15, 1997


The Antique Telescope Society, an international society of collectors,
researchers, students, museums and librarians with an interest in the
history of the telescope and related astronomia will host its 6th annual
convention in Southern California. Venues include: Mt. Wilson
Observatory, Griffith Observatory, Hale's Solar Lab, Cal Tech & Palomar
Observatory. The convention is open to members and guests of the society,
including the general public. You do NOT have to be a member of the
society to attend (although it is more economical to do so). In the past,
ATS conventions have been first class gatherings in such places as Bath,
England, Washington D.C. (USN Observatory), Yerkes, Lick, Ricard, Sproul,
Chabot observatories and others.

"Will we get to use any of the large historic instruments?" - Yes,
currently, we have time reserved on the 60" Reflector at Mt. Wilson -
weather permitting.

"What do we do at these conventions?"  - See great telescopes and
observatories with significant historical records ... Hear great
presentations related to telescopes, telescope makers, observatories, and
related topics ... Eat good food ... See members' collectible telescopes
... Observe with large, historic instruments ... Get the "insider's" tour
of these historic locations (you will get to see what the general public
rarely gets to see) ... Make acquaintances from all over the country and
other countries as well.

"What does it cost?" - Prices haven't been set, but in every past
convention, the perception of the members is that the value of the
convention FAR exceeded the cost. In all cases, the ATS tries to do things
in a first class manner and it has shown in the increased attendance and
growth of the society.

"How do I sign up?" - Email Bart Fried at nuvista@compuserve.com for
further information. As the convention gets closer, details will be
finalized and a packet will be available for anyone who wishes to consider
attending.

Schoener from 1515 and globes by van Langren, Homann, Andreae, Doppelmayr,
Klinger and Franz); 29 sundials (by Ritter, Scriba, Nieborg, Willebrand,
Feriary, Baradelle, Vogler, Mueller, Grassl, Keller, Neringer); 5
instruments used in the construction of sundials; 10 astrolabes and related
instruments (among them Islamic from the 12th c., Islamic from the period
around 1700, two French pieces from the 15th c., from the Lower Rhine from
the 16th c.); 5 instruments from Erasmus Habermel around 1600 (sundials, a
horological slide rule and a theodolite); 3 "Aequatorien"; 6 planetariums
and world models; 9 telescopes and observational instruments (by
Semitecolo, Deregni, Willson, Utzschneider and Fraunhofer, Steinheil,

Observatory in Berlin-Treptow was reopened. On the 12th October the
observatory celebrated its 100th anniversary. The astronomical museum
could not yet be opened again, however there are display cases in the hall
in which the history of the observatory and the history of astronomy in
general are depicted. On exhibit are three instruments from the workshop of
R. Toepfer (Potsdam) from around 1950 (Hartmann microphotometer, plate
measuring instrument, spectroscope), the telescope of the Berlin "street
astronomer" Max Kutscher from 1950 and one theodolite.

The Orgelbaumuseum Schloss Hanstein [Organ Museum Castle Hanstein] in
Ostheim (Rhoen) commemorates also Cuntz von der Tann (1567-1639), a
knighted captain and inhabitant of the castle. He owned astronomical
instruments and built an observational room in the castle's attic. From
his diarys, it is clear that he was in contact with both Tycho Brahe und
Johannes Kepler. - The museum would be interested in acquiring more
information on the activities of Cuntz von der Tann. His diarys have up
until today not been completely evaluated. The archives of the family von
Tann are located in Deutsches Adelsarchiv, Schwanalle 21, 3D5037 Marburg,

Memorials
---------

In June 1993 a memorial plaque was erected at the birth house of Friedrich
Simon Archenhold (1861-1939) in Lichtenau (Westfalen, Germany; Lange
Strasse 22) in memory of the founder of the Treptow Observatory.
Source: D. B. Herrmann, Blick in das Weltall, Berlin 1994, p. 79.

On April 21, 1995, on the occasion of the 500th birthday of Peter
Apian a memorial plaque was finally put in place at the house Markt 13 in
Leisnig (Sachsen, Germany). It is the site, most likely, where Apian was
born. The original building is said to have been burned to the ground by
fire in 1700. The exact location of his birth is not known. However,
there were several reasons why Leisnig was chosen. At the same house a
coat of arms dating back to May 23, 1870, is put up, with an
inscription pointing at Apian. In Leisnig also public places have been
dedicated to the astronomer and cartographer: Peter-Apian-Platz and
Peter-Apian-Mittelschule. - The Grossgemeinde [united municipality]
Seubersdorf (Oberpfalz, Germany) named in 1995 a small street in
Ittelhofen, in the vicinity of the church, after Apian; in April 1995 a
street sign was erected at Apianstrasse. The Hofmark [farm march]
Ittelhofen belonged to Apian since 1544. In the church of Ittelhofen can
be found an epitaph for Apian's son Claudius as well as one for his son
Karl (Carolus) and Karl's wife Ursula.

On March 20, 1996, a memorial plaque was erected on the director's house of
the Jena University Observatory (Schillergaesschen 3) for Hermann Lambrecht
(1908-1983), which was donated by the Gesellschaft der Freunde und
Foerderer [Society of Friends and Patrons] of the Friedrich Schiller
University at Jena.

On the occasion of the 400th anniversary of the discovery of Mira in
Resterhafe (Ostfriesland) the local parish has placed a memorial plaque
on the outside of the church in Resterhafe in memory of David Fabricius
(1564-1617). The unveiling took place on August 31, 1996.

On September 13, 1996, a bronze relief of Tycho Brahe was unveiled in
Rostock on the building used by the Rostocker Volksbank (Glatter Aal). The
relief was done by Jo Jastram, and was funded by the Volksbank. A sundial
was also commemorated on the same day. On the sundial the world system of
Tycho Brahe is depicted as well as the symbols of the zodiac.

On November 19, 1996, on the occasion of the 150th anniversary of the
Carl Zeiss enterprise, the reconstructed monument to Ernst Abbe was
rededicated on the Carl-Zeiss-Platz in Jena, Germany.
