Sir Jagadis Chandra Bose, FRS was the first experimental physicist from British India (today's Indian subcontinent) who received international recognition through his pioneering work on millimetre wave physics, wireless radio propagation and plant physiology (biophysics). In many of his research areas he was well ahead of his time. Sir Jagadis was born on November 30, 1858 in Meymensingh, East Bengal (now Bangladesh). He was educated at St. Xavier's college in Kolkata (Calcutta), Christ College of Cambridge University as well as the University College of London. In 1885 he was appointed as the professor of physics in Presidency College of Calcutta University. On his 59th birthday, the 30 November 1917 he founded the Bose Institute (BI) in Calcutta. The Sir J.C. Bose Institute is now a prime national establishment in India with vigorous research as well as post graduate education activities on many important facets of life and environmental science, physics and chemistry. Recently a centre for space science, astroparticle physics and cosmology has been established under the BI. Since its very inception, Sir Jagadis himself carefully preserved and displayed the scientific apparatus and equipments developed and constructed by his team made of local craftsmen and students, thereby created the very foundation of the Bose Institute museum, which transformed into a renowned technology-historical museum in India during the period 1986-87. Our talk will highlight the historical development of the Sir J.C. Bose Institute Museum and important exhibits and interesting collections using photographic and multimedia presentations. Sir Jagadis passed away on November 28, 1937 in Giridih, province of Bihar, North-East India. His tomb is situated at the main lawn of the institute.","PeriodicalId":138843,"journal":{"name":"2008 IEEE History of Telecommunications Conference","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115669733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet the radar work itself was an outgrowth of work beginning circa 1920 on improving the performance of communication systems in the presence of noise. We have previously reported on work carried out in this area during the 1920s in both radio (wireless) communications and wired telephony [1]. In this paper we focus on work done in the 1930s and early 1940s, which both enlarged on, and saw considerable strides ahead in, these earlier studies involving noise in communication systems. We do this by presenting developments during this period of time in three inter-related, and roughly chronological, areas: 1. Work by Armstrong on FM and Reeves on PCM showing, for the first time, that noise could be reduced by purposefully increasing the bandwidth (now known as the noise-bandwidth tradeoff). This work is discussed in the next section covering the period of the 1930s. 2. Studies attempting to understand the statistical properties of noise, leading to its now-well-known Gaussian amplitude characteristic. This work is described in the section covering the late 1930s to early 1940s. 3. The recognition that ldquomatched filteringrdquo provided optimum signal detection in noise. This work, described in the last section of this paper, arose out of the need during World War II to detect small, pulsed, radar signals in the presence of noise.","PeriodicalId":138843,"journal":{"name":"2008 IEEE History of Telecommunications Conference","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124545189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet one category of major contributor to the development of the discipline is rarely considered in detail: the engineering educator. This paper presents the contribution of one of the outstanding teachers of electronics of the twentieth century - in particular, a teacher of the communications networks, circuit theory and filter design so important to modern telecommunication systems - Ernst (Ernie) Guillemin. Guillemin studied electrical engineering at Wisconsin and MIT. He was granted a Saltonstall Traveling Fellowship which allowed him to study under Arnold Sommerfeld in Munich, gaining a PhD there in 1926. He returned to MIT and spent the majority of his career there, working first with Vannevar Bush, and then contributing to various wartime projects in the MIT Radiation Laboratory. Guillemin became full professor in 1944, concentrated increasingly on network theory in his teaching and research, and was awarded various medals and honours over the next two decades. He died on 6 April 1970. Guilleminpsilas major pedagogical legacy is a magisterial series of six sole-authored books together with substantial contributions to two of MITpsilas renowned ldquoblue booksrdquo - the text books authored by MIT staff as the EE curriculum was modernised in the late 1930s and 1940s. This paper aims to demonstrate why his name became a by-word for excellence in electronics engineering education, and why a several generations of former students and colleagues revere him and his legacy.","PeriodicalId":138843,"journal":{"name":"2008 IEEE History of Telecommunications Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125791560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
