Mannone: A Propensity for Genius A Propensity for Genius: That Something Special About Fritz Zwicky (1898 - 1974) by John Charles Mannone Preface It is difficult to write just a few words about a man who was so great. It is even more difficult to try to capture the nuances of his character, including his propensity for genius as well as his eccentric behavior edging the abrasive as much as the funny, the scope of his contributions, the size of his heart, and the impact on society that the distinguished physicist, Fritz Zwicky (1898- 1974), has made. So I am not going to try to serve that injustice, rather I will construct a collage, which are cameos of his life and accomplishments. In this way, you, the reader, will hopefully be left with a sense of his greatness and a desire to learn more about him. -
Reflections December 2020
Surviving the Bobcat Fire By Robert Anderson As recently as December 9, our solar astronomer, Steve Padilla, was taking his evening walk and noticed the smoke of a hotspot flaring up in the canyon just below the Observatory. It was a remnant of the Bobcat Fire, which started nearby on September 6. The local Angeles National Forest firefighters were notified of the flareup, either to monitor it or extinguish it if needed. They have returned many times during the last three months. And we are always glad to see them, especially those individuals who put water to flame here and battled to save the most productive and famous observatory in history. On the sunny Labor Day weekend, when the Bobcat Fire started near Cogswell Reservoir in a canyon east of the Mount Wilson, the Observatory’s maintenance staff went on cautious alert. As the fire spread out of control, it stayed to the east burning north and south of the reservoir for days, threatening communities in the foothills of the San Gabriels. Nevertheless, all non-essential staff and residents were evacuated off the mountain just in case. Under a surreal, smoke-filled September sky, crews David Cendejas, the superintendent of the Observatory, prepare to defend the Observatory. Photo: D.

It replaced the old observatory located at Millerntor on the western part of the ramparts around the core of Hamburg City. At the time, the new facility in Hamburg-Bergedorf was considered to be among the most modern and largest of Europe. About 20 kilometers away from the city centre, it was placed on a hill and extended over an area of some seven hectares that resembled a park. The facility consists of the main building, three residential buildings, several domes, the solar building and sheds for the various telescopes. There were several ancillary buildings, too. The design of the facility can be termed modern in that it was placed on a hill and far away from the city. Also, the fact that the instruments were housed in several buildings spread over the entire grounds was a new feature. The Hamburg Observatory is one of the first where the principle of setting up the instruments in a large ensemble of buildings was consistently put into practice. -
Astrometry 1960-80: from Hamburg to Hipparcos by Erik Høg, 2014.08.06 Niels Bohr Institute, Copenhagen University
Astrometry 1960-80: from Hamburg to Hipparcos By Erik Høg, 2014.08.06 Niels Bohr Institute, Copenhagen University ABSTRACT: Astrometry, the most ancient branch of astronomy, was facing extinction during much of the 20th century in the competition with astrophysics. The revival of astrometry came with the European astrometry satellite Hipparcos, approved by ESA in 1980 and launched 1989. Photon-counting astrometry was the basic measuring technique in Hipparcos, a technique invented by the author in 1960 in Hamburg. The technique was implemented on the Repsold meridian circle for the Hamburg expedition to Perth in Western Australia where it worked well during 1967- 72. This success paved the way for space astrometry, pioneered in France and implemented on Hipparcos. This report gives a detailed personal account of my life and work in Hamburg Bergedorf where I lived with my family half a century ago. The report has been published in the proceedings of the meeting in Hamburg on 24 Sep. 2012 of Arbeitskreis Astronomiegeschichte of the Astronomische Gesellschaft.

Bernhard Schmidt (1879-1935) Óptico E
BERNHARD SCHMIDT (1879-1935) ÓPTICO E CONSTRUTOR DE TELESCÓPIOS PEDRO RÉ http://www.astrosurf.com/re Bernhard Schmidt é famoso por ter inventado e construído um novo tipo de telescópio (telescópio de Schmidt) que tem a particularidade de apresentar uma elevada correcção no que diz respeito a diversos tipos de aberrações (esférica, coma e astigmatismo) (Figura 1). Bernhard Schmidt nasceu na Estónia em 30 de Março de 1879. Foi o primogénito de 6 irmãos. A sua família era originária da ilha de Naissaar (costa de Tallinn – mar Báltico). O seu pai, Karl Konstantin Schmidt, além de escritor, era igualmente agricultor e pescador. A língua oficial em Naissar era o sueco mas os Schmidt falavam alemão em casa. Aos 15 anos de idade, B. Schmidt perdeu o antebraço e a mão direita num acidente com pólvora. Em 1895 Bernhard muda-se para Tallinn onde trabalha como operador de telégrafo. Entre os anos de 1895 e 1901 trabalha igualmente como fotógrafo. Em 1900 constoi a sua primeira objectiva com 5” de diametro e realiza diversas observações de uma estrela Nova que surgiu na constelação do Perseu em 1901. Nesse mesmo ano parte para Gotenburgo com a intenção de frequentar a Universidade de Chalmers e mais tarde muda-se para Mittweida na Alemanha onde termina os seus estudos. Durante este período o seu interesse pela astronomia e pela construção de telescópios aumenta consideravelmente. Em Mittweida tenta trabalhar com Karl Strehl (1864-1940) sem sucesso. Entre os anos de 1901 e 1903 constrói numerosos espelhos que foram sobretudo vendidos a astrónomos amadores e em 1903 termina um espelho para o observatório de Alterburg. -

A medium-band 12-color photometric system, based on the decon- taminated Gaia BP/RP spectra, has been proposed in our Paper II. Here we analyze a possibility to apply some versions of this system for the determina- tion of temperatures and gravities of stars both in the absence and the presence of interstellar reddening. The possibility to supplement this system with the broad BP and RP passbands is verified. We conclude that the system gives an acceptable accuracy of temperatures and luminosities if the accuracy of color indices is 0.02 mag or better and if the parallaxes of stars are known.

Estimation of time delays from a noisy and gapped data is one of the simplest data analysis problems in astronomy by its formulation.

O STER BROCK Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1983 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. RUDOLPH LEO BERNHARD MINKOWSKI May 28, 1895-January 4, 1976 BY DONALD E. OSTERBROCK UDOLPH MINKOWSKI was born in Germany near the end R of the last century and died in California during the final quarter of this century. He was trained as a laboratory physicist, but worked most of his life as an observational astronomer. Using the largest optical telescopes in the world, he made important contributions to nearly every branch of nebular and extragalactic astronomy, but his most important contribution of all was to the identification and interpretation of cosmic radio sources. His monument is the National Geographic Society-Palomar Observatory Sky Survey. He guided, encouraged, and counseled a generation of radio and optical astronomers. Minkowski was born in Strassburg, then part of Germany, on May 28, 1895. His grandfather had hurriedly moved his family to Konigsberg from their native Russia less than twenty-five years before to escape the policy of anti-Semitic persecution adopted by the Czar's government. Rudolph's father Oskar, educated in Konigsberg, became a physician, and at the time of Rudolph's birth he was a well-known pathologist on the Strassburg University medical faculty. His research had played a very important part in understanding the causes of diabetes. -

Fascinated by the stars and planets in the dark sky over Lolland, an island 100 km south of Copenhagen, the interest in astronomy was growing. Encouraged by my teachers, I polished mirrors and built telescopes with generous help from the local blacksmith and I observed light curves of variable stars. Studies at the Copenhagen University from 1950 gradually led me deeper into astronomy, especially astrometry (the astronomy of positions), guided by professor Bengt Strömgren and my mentor dr. phil. Peter Naur. I was lucky to take part in the buildup of the new observatory at Brorfelde during the first difficult years and the ideas I gathered there have contributed to the two astrometry satellites Hipparcos and Gaia launched by the European Space Agency (ESA) in respectively 1989 and 2013. – The account contains notes about Danish astronomers and the observatory, but it is not meant to be a history of Danish astronomy; it is my personal memoirs. 1 On the island Lolland Born in 1932, I lived in the 1930s and 40s in a rural area typical for the province of Denmark in those years. -
