Sir Arthur Conan Doyle (1859-1930), English physicist, writer and detective storyteller who invented the character of Sherlock Holmes and Dr Watson, was a member of Phoenix Lodge No. 257 in Portsmouth.

The Capitol in Washington, D.C. was originally designed by William Thornton, built by Benjamin Latrobe and later completed by Thomas Walter, all three Freemasons. The cornerstone of the Capitol in Washington, D.C. was laid by President George Washington in 1793 according to the Masonic rite. The Marquis de La Fayette ceremonially presented him with the Masonic apron made for him by the Grand Lodge of Maryland.

The first Asian Masonic Lodge was founded in Calcutta, India, in 1729. Captain Ralph Farrwinter, an officer of the East India Company, was appointed Provincial Grand Master for the East Indies and granted the patent for the first Indian lodge ‘East India Arms, No. 72’, based in Fort William, Calcutta. This marked the beginning of the long Masonic tradition on the Asian continent.

Modern Freemasonry only emerged in 1717 - long after the death of Leonardo da Vinci in 1519. Although his works contain geometric and symbolic elements that also play a role in Freemasonry, there is no historical evidence of a direct connection. Theories about secret messages in his paintings are speculative and lack a reliable basis.

Almost 3,500 members in over 80 lodges belong to the Grand Loge Alpina of Switzerland. In addition, around 1,000 freemasons are members of the Grand Orient de Suisse, the Grand Loge Féminine de Suisse, the Grande Loge Mixte de Suisse and the Droit Humain, which is also mixed-gender.

Even though the essence of Freemasonry is discussed in the conversations in Thomas Mann's ‘The Magic Mountain’, Mann himself was not a Freemason.

Carl von Ossietzky was a member of the Hamburg lodge ‘Menschentum’, Lessing of the Hamburg lodge ‘Zu den drei Rosen’ and Tucholsky of the Berlin lodge ‘Zur Morgenröte’.

Jonas Furrer was the first Federal President of modern Switzerland from 1848 and the first Grand Orator in the Directorate of the Grand Loge Alpina of Switzerland, which was founded in 1844. Hottinger was the first Grand Master, Druey was a Freemason, but not a member of the Directorate of the Grand Lodge, and Munzinger was not a Freemason.

Even though the foundation of the Nobel Prize has certain parallels with Masonic ideals, Alfred Nobel (1833-1896) was not himself a member of a lodge. Gustave Eiffel (1832-1923) was a member of a lodge of the Grand Orient de France, Theodor Tobler (1876-1941) was a member of the Bernese lodge ‘Zur Hoffnung’ and André Citroën (1878-1935) of the lodge ‘La Philosophie positive’ of the Grand Orient de France.

Since the office was founded in 1789, 45 people have held the office of US President. Of these, 15 are known to have been Freemasons, beginning with George Washington as the first president. The last undisputed Freemason among them was Gerald Ford. Ronald Reagan received an honorary membership in 1988, and Joe Biden was proclaimed a ‘Mason at Sight’ by the Prince Hall Grand Lodge of South Carolina in 2025, although it is disputed whether he actually accepted the membership.

In Freemasonry, the rough stone (ashlar) symbolises a person's imperfect, natural personality, which is to be refined through work on oneself. Just as a stone is hewn and smoothed to fit into a building, the Freemason should mould and improve his character traits. This symbolic process stands for personal development, ethical education and the constant search for (self-)realisation and perfection.

Freemasonry is considered a secretive society because it does not publicise the personal experiences and exchanges between members or its rituals and symbols. This discretion serves to protect individual development and the free expression of opinions within the lodge. At the same time, its values and goals are open to public scrutiny, which is why it is not a secret society but a discreet community.

The Roman Catholic Church prohibits its faithful from becoming members of Freemasonry, as it considers its principles to be incompatible with church doctrine. The 1983 declaration of the Congregation for the Doctrine of the Faith emphasises that Catholics who become Freemasons are living in a state of grave sin and are not admitted to Holy Communion. The main reproach lies in the Masonic world view, which is regarded as relativistic and contradicts the exclusive truth of the Church.

A Freemason does not have to be a Christian, but merely believe in a superior power or a principle of divine order. Many lodges include members of many different religions, including Jews, Muslims, Hindus and Buddhists. While some Masonic systems are of Christian origin, Freemasonry itself is not a religious organisation.

Modern freemasonry originated from the stonemason brotherhoods of the cathedral building lodges of the late Middle Ages, which cultivated operative rules of the trade and symbolic rituals.

In contrast, ancient Egyptian mystery cults originated from religious initiation traditions with no direct connection to Freemasonry. The Knights Templar, a medieval order of knights with a military-religious character, also has no demonstrable historical continuity with Freemasonry. Similarly, there is no direct link to the Order of the Garter, an elite British chivalric order whose aristocratic structure and objectives differ fundamentally from the Masonic idea of equality.

The Grand Master and the Directorate are elected every four years by the Assembly of Delegates of all Swiss lodges.

Johannes Brahms was not a freemason. Franz Liszt, on the other hand, belonged to the lodge ‘Zur Einigkeit’ in Frankfurt, Jean Sibelius to the Finnish lodge no. 1 ‘Suomi Lodge No. 1’ and Clérambault to the Parisian lodge ‘Coustos-Villeroy’.

The Temple of Solomon is the educational image of the Freemasons. The Freemasons are building a temple that is still unfinished. It is the temple of humanity, symbolising a world in which people live together peacefully in a spirit of tolerance, in all the diversity of their cultures and world views.

Freemasonry is banned in many totalitarian states because it advocates individual freedom, humanity and freedom of expression - values that authoritarian regimes often see as a threat. As Masonic lodges are independent and do not accept state influence, they are seen as potential opposition groups in dictatorships. In addition, totalitarian regimes mistrust the discretion and international connections of Freemasonry, which is why they often categorise it as subversive or anti-state.

The following seven Federal Councillors were Freemasons:

• Jonas Furrer (‘Akazia’, Winterthur) from 1848
• Henri Druey (‘Espérance et Cordialité’, Lausanne) from 1848
• Eugène Borel (‘La Bonne Harmonie’, Neuchâtel) from 1875
• Louis Ruchonnet (‘Liberté’, Lausanne) from 1893
• Emil Frey (‘Zur Freundschaft und Beständigkeit’, Basel) from 1897
• Marc Ruchet (‘Liberté’, Lausanne) from 1899
• Adrien Lachenal (‘Fidélité et Prudence’, Geneva) from 1899

The charitable commitment of Freemasons is reflected in regular donations and support for charitable causes, which are collected at lodge meetings. Many lodges support social projects, educational initiatives or charitable organisations at local, regional and international level. The focus here is on helping quietly, without public self-promotion or missionary intentions.

The motto ‘Liberté, Égalité, Fraternité’ (Liberty, Equality, Fraternity) became a central motto during the French Revolution and is still the national motto of France today. It reflects ideals that are also important in Freemasonry, as it advocates personal freedom, social equality and fraternal solidarity. Many revolutionaries, including the Marquis de Lafayette and Joseph-Ignace Guillotin, were Freemasons, but the movement itself was not driven by Freemasonry. Rather, both shared ideas of enlightenment and progress.

Freemasonry consists of various obediences (grand lodges) that are organised independently of each other and maintain different rituals and traditions. Some emphasise spiritual and philosophical aspects, while others are more socially committed. There are also all-male, all-female and mixed obediences, which differ in their structure and orientation, but all share the fundamental principle of masonic work on themselves and society.

To become a Freemason, you have to register with a lodge or grand lodge independently, as Freemasonry does not actively recruit members. Motivation and personal suitability in relation to Masonic values are assessed in an examination procedure involving several interviews. Neither inheritance nor family connections or financial means are decisive for admission - only the personality and inner attitude of the candidate are decisive.

Masonic values are universal and based on the principles of the Enlightenment, which is why they appeal to different political spectrums. Liberty, equality and fraternity appeal to liberal and social movements, while tolerance and humanity also play a role in conservative and Christian ideologies. As Freemasonry is not a political party, but conveys ethical principles, its values can be taken up and interpreted by different political movements.
