Reporting for SpaceWatchtower
Yesterday (March 24), Al Paslow, a
member of the Antique Telescope Society, and members of a demolition
crew opened a time capsule, a small brass box sealed with solder,
that had been placed inside a cornerstone of the now-demolished
Brashear Telescope Factory building on the North Side of Pittsburgh.
The building, built in May of 1886 and added to the National Register of Historic Places in 2012, was originally the home of the
John A. Brashear Company which had manufactured hundreds of
telescopes and precise scientific instruments for observatories and
scientific institutions throughout the world, in the latter part of the nineteenth century and the first half of the twentieth century.
Demolition of the historic building,
which had been vacant for about 20 years, was necessitated after a
wall of the building collapsed onto a nearby two-floor apartment
building on March 16. The apartment building had to be evacuated,
until city inspectors declared the building safe for occupancy.
Jadell Minniefield Construction Company, of the Hazelwood section of
Pittsburgh, demolished the Brashear Telescope Factory building under
an emergency demolition order issued by Maura Kennedy, who heads the City of Pittsburgh's Department of Permits, Licenses, and Inspections.
While inspecting the remains of the
nearly-demolished building yesterday, members of the demolition crew
showed Al Paslow a time capsule that had been found near a building
cornerstone a few days earlier. After calls to several societies and
organizations went without result, it was decided that Al Paslow and
three members of the demolition crew would open the time capsule and
photo-document the contents.
As displayed at the beginning of this
blog post, one photograph in the time capsule shows employees of the
Mechanical Department of the John A. Brashear Company. The photograph
is dated August of 1894, which is eight years after the
construction of the Brashear Telescope Factory building. So,
unlike most building time capsules, apparently this time capsule was
installed after building completion, instead of during the laying of the building's cornerstone.
The time capsule also included:
- a letter from John Brashear;
- newspaper articles from 1891 to 1894 August 9;
- photographs of John Brashear's family, including his mother and father;
- photographs of prominent citizens of Pittsburgh and Allegheny City (Pittsburgh's "twin city" at that time, where the factory and Allegheny Observatory were actually located, Allegheny City was annexed to Pittsburgh in 1907 and became Pittsburgh's North Side);
- a piece of glass with the inscription, “One of the first pieces of Optical glass Made in America”;
- a lock of hair from John Brashear's wife, Phoebe, inside a small envelope so-labeled;
- a letter from Worcester Reed Warner and Ambrose Swasey, owners of Cleveland telescope manufacturer Warner and Swasey Company, congratulating the Brashear Company on the completion of the new factory building (Brashear and Warner and Swasey collaborated on several projects);
- a book labeled, “In Memoriam William Thaw.” complete with photographs (John Brashear's mentor who had paid for the land and construction of the factory building, William Thaw had died in 1889);
- at the bottom of the time capsule box were plans and blueprints for the factory building.
In an electronic mail message
distributed over the Antique Telescope Society's mail-group (copied
over the History of Astronomy mail-group by John W. Briggs)
yesterday, Al Paslow wrote, “Most of the contents of the Time
Capsule are in remarkable shape; however some older photographs are
faded but many look as good as the day they were left inside.” He
has placed many photographs of the time capsule contents on his
personal Internet web site (a link to this web site is at the end of this blog post).
The wall collapse had occurred on March
16, with demolition of the rest of the building beginning the next
day. When the author of this SpaceWatchtower blog, Glenn A. Walsh,
viewed the site on the evening of the Vernal Equinox (March 20, the official beginning of the season of Spring), the
majority of the building had been brought-down, with the exception of
small portions of the north and south walls. In his March 24 e-mail
message, Al Paslow reported that the demolition was completed, and
the site has been covered in straw, as of Tuesday afternoon (March
24).
Al Paslow did not mention the disposition of
the time capsule and contents in his message. As, at the time of demolition, the
Brashear Telescope Factory building was legally owned by the City of
Pittsburgh, the time capsule and contents would be the legal property
of the City.

Very Interesting post. I have been wondering about this and your written in such a way that it is clearly understood. Thank you.
ReplyDeleteI have some relevant information you can review below.

Brashear was indeed an extraordinary telescope-maker. His refractors are legendary as they usually had the flint element in front of the crown one.
ReplyDeleteits amazing post.i am looking for this type of postTelescope Manufacturers
ReplyDeleteHey very nice post!! Thank you so much for sharing it..I know one site that provides products include telescope, red dot sight, rifle scope and binocular. They have a creative and experienced R&D team concentrating on market demand and innovation. Just have a look http://www.bosmaoptics.com/
