 Mendel 's work went largely unnoticed after its first publication in 1866 , but was rediscovered in the late 19th @-@ century by Hugo de Vries , Carl Correns , and Erich von Tschermak , who ( claimed to have ) reached similar conclusions in their own research . Specifically , in 1889 , Hugo de Vries published his book Intracellular Pangenesis , in which he postulated that different characters have individual hereditary carriers and that inheritance of specific traits in organisms comes in particles . De Vries called these units " pangenes " ( Pangens in German ) , after Darwin 's 1868 pangenesis theory .

 The father of genetics is Gregor Mendel , a late 19th @-@ century scientist and Augustinian friar . Mendel studied ' trait inheritance ' , patterns in the way traits were handed down from parents to offspring . He observed that organisms ( pea plants ) inherit traits by way of discrete " units of inheritance " . This term , still used today , is a somewhat ambiguous definition of what is referred to as a gene . 

neutral
 Scientists looking back on the Avery – MacLeod – McCarty experiment have disagreed about just how influential it was in the 1940s and early 1950s . Gunther Stent suggested that it was largely ignored , and only celebrated afterwards — similarly to Gregor Mendel 's work decades before the rise of genetics . Others , such as Joshua Lederberg and Leslie C. Dunn , attest to its early significance and cite the experiment as the beginning of molecular genetics .

 As a Harvard undergraduate , Kaczynski was among twenty @-@ two students who were research subjects in ethically questionable experiments conducted by psychology professor Henry Murray from late 1959 to early 1962 .

 Reich sent a sample of the bacteria to a Norwegian biologist , Theodor Thjøtta of the Oslo Bacteriological Institute , who also blamed airborne infection . Kreyberg and Thjøtta 's views were published in the country 's largest newspaper , Aftenposten , on 19 and 21 April 1938 . Kreyberg alleged that " Mr. Reich " knew less about bacteria and anatomy than a first @-@ year medical student . When Reich requested a detailed control study , Kreyberg responded that his work did not merit it .
