Raoul-Pierre Pictet was a Swiss physicist. Pictet is co-credited with French scientist Louis-Paul Cailletet as the first to produce liquid oxygen in 1877.
Pictet is a lunar impact crater located just to the east of the larger and more prominent impact crater Tycho. The high-albedo rays and ejecta from Tycho lie across Pictet and spread far to the east and in other directions. Pictet is older than Tycho and is somewhat worn by past impacts. The slightly smaller crater Pictet A intrudes slightly into the southwest rim. The larger crater Pictet E is nearly joined to the north rim. To the east is Saussure,and to the northeast is the larger,worn formation Orontius.
François Jules Pictet-De la Rive was a Swiss zoologist and palaeontologist.
The Pictet–Spengler reaction is a chemical reaction in which a β-arylethylamine undergoes condensation with an aldehyde or ketone followed by ring closure. The reaction was first discovered in 1911 by AméPictet and Theodor Spengler. Traditionally,an acidic catalyst in protic solvent was employed with heating;however,the reaction has been shown to work in aprotic media in superior yields and sometimes without acid catalysis. The Pictet–Spengler reaction can be considered a special case of the Mannich reaction,which follows a similar reaction pathway. The driving force for this reaction is the electrophilicity of the iminium ion generated from the condensation of the aldehyde and amine under acid conditions. This explains the need for an acid catalyst in most cases,as the imine is not electrophilic enough for ring closure but the iminium ion is capable of undergoing the reaction.
The Bischler–Napieralski reaction is an intramolecular electrophilic aromatic substitution reaction that allows for the cyclization of β-arylethylamides or β-arylethylcarbamates. It was first discovered in 1893 by August Bischler and Bernard Napieralski,in affiliation with Basel Chemical Works and the University of Zurich. The reaction is most notably used in the synthesis of dihydroisoquinolines,which can be subsequently oxidized to isoquinolines.

3,4-Dimethoxyphenethylamine (DMPEA) is a chemical compound of the phenethylamine class. It is an analogue of the major human neurotransmitter dopamine where the 3- and 4-position hydroxy groups have been replaced with methoxy groups. It is also closely related to mescaline which is 3,4,5-trimethoxyphenethylamine.

His actions were partially responsible for the creation of the Canton of Geneva which was finalized in 1814-15 at the Congress of Vienna.

The Prix Pictet is an international award in photography. It was founded in 2008 by the Geneva-based Pictet Group with the mandate to use the power of photography to communicate messages about sustainability to a global audience. Its goal is to uncover photography of the highest order,applied to current social and environmental challenges. With the participation of over 4,700 photographers,the prize is judged by an independent jury and carries a prize of CHF 100,000. Since 2008 the ten cycles of the Prix Pictet have been shown in more than 100 exhibitions across 25 countries with visitor numbers of over 550,000. The ten Prix Pictet winners are Benoit Aquin,Nadav Kander,Mitch Epstein,Luc Delahaye,Michael Schmidt,Valérie Belin,Richard Mosse,Joana Choumali,Sally Mann and Gauri Gill.
