Industry Pioneers: Peter Ellis - the Father of the Paternoster


Peter Ellis was born on 1 August 1805 at Shaw's Brow (later renamed William Brown Street) in Liverpool. He was the third son in a family of seven; his parents were Peter Ellis Senior and Ann Ellis (née Appleton). Peter Ellis Senior was an architect who worked on the construction of Courts in an area now buried under Lime Street Station. It was perhaps no surprise when Peter followed in his father’s footsteps and became an architect. He was first mentioned in Gore's Liverpool Directory in 1834 as an architect with an office on Renshaw Street but prior to that he had learned his trade working with his father developing terrace properties for residential use. 

What did he do?

Ellis had a fairly prolific career and worked on many buildings in the Liverpool area in from the 1820s right up 1884, the year of his death. He died at the age of 79 at his home at 40 Falkner Square on 20 October 1884. Of all the buildings that he worked on he is best known for two of his commissions; Oriel Chambers built in 1864 and 16 Cook Street built in 1866. The Cook Street building had a spiral staircase, cantilevered out from the main building and clad with sheets of iron and glass. Oriel Chambers took its name from the type of windows used was in the construction. Oriel Chambers became Ellis’ most notable contribution to the architectural community in the United Kingdom and around the world. Oriel windows are a type of bay window that project from the main wall of a building but do not reach the ground. Oriel windows are supported by corbels, brackets or similar and are most commonly found projecting from an upper floor but have also been used on the ground floor. 

How does this relate to the Vertical Transportation industry?

Designed and built by Ellis, Oriel Chambers contained the world’s first Paternoster-style lift. Ellis received a lot criticism from the architectural community for Oriel Chambers at the time of its construction and his career suffered a loss of momentum.  Many years later Oriel Chambers was praised for being one of the first office buildings to use an iron framework structure and oriel windows and Ellis was finally acknowledged as a pioneer. The innovative design has also been recognised as a precursor to Modernism and a source of inspiration for John Root’s early Chicago skyscrapers. From a vertical transportation perspective, Ellis is recognised as the Father of the Paternoster lift.  Ellis had filed a patent* for a ‘continuously moving lift’ in 1866, it was granted the following year and the Paternoster lift at Oriel Chambers was installed in October 1869. Paternosters went onto become very popular during the first half of the 20th century, particularly in Eastern Europe. You can read more about paternosters in our post, ‘here’.

Should the Paternoster lift be confined to History?

The paternoster lift takes its name from the first two words of the Lord’s Prayer - “paternoster,” or “Our Father” in Latin. The image of a moving chain decorated by small, individual compartments reminded its designers of rosary beads being turned in people’s hands whilst praying, which is how it got its name. The first paternoster-style lifts were installed in Oriel Chambers, Liverpool in 1868 and were designed by the architect Peter Ellis. In 1876 a German company R Stahl* installed a paternoster London’s General Post Office. However, in 1877, British engineer Peter Hart obtained a patent on a paternoster design. Then in 1884, the Dartford, England, engineering firm of J & E Hall built its "Cyclic Elevator”. Paternoster lifts comprise of a chain of open compartments (each usually designed for two persons) that move slowly in a loop up and down inside a building without stopping.

Where was the Paternoster lift popular?

Paternoster lifts were popular in Europe during the first half of the twentieth-century, but their use led to numerous health and safety concerns. These concerns were understandable. The fact that paternosters do not stop means they are particularly dangerous for the elderly, disabled and children to use. Add to this the fact that paternosters are door-less and it is easy to appreciate how accidents could happen and unfortunately they did happen and some included fatalities. Riding a paternoster is no time to be staring at your smartphone; timing your steps on and off the lift demands total concentration. The poor safety record of paternosters has led to them being described as ‘death traps’ in some circles.

When was the Paternoster lift banned from manufacture?

By the 1970s this poor safety record led to new paternoster installations being banned in many countries across Europe. Germany banned new installations of paternosters in 1974. In recent times government initiatives to remove the remaining 250 operational paternosters in Germany have met with a fairly surprising public backlash. Supporters of paternosters claimed they had efficient design and perhaps nostalgia caused them to overlook safety concerns. In the UK British National Standards Related to Lifts, Escalators and Moving Walks were updated with BS2655 Part 5 in 1970 that specifically outlined safety requirements for paternosters. All of the UK’s paternosters in service had been constructed before BS2655 Part 5 was introduced. 

Did any manufacturer ever improve upon the design?

In 2013 Hitachi introduced a design for a Circulating Multi-Car Elevator System that appears similar to a paternoster but has two additional benefits – the lift cars are independent of each other and are able to stop like conventional lifts. In the Hitachi prototype lifts are counterweighted against each other. You can see the set up here 

Safety first: Yes, Paternosters should be confined to history?

Given the number of accidents that have occurred with passengers travelling on paternosters it seems sensible that they are confined to history. It is extremely unlikely that new paternoster installations will be constructed anywhere in the world. It remains to be seen whether architects and building contractors have any appetite for paternoster –style vertical transportation systems such as the Circulating Multi-Car Elevator System designed by Hitachi.

However, contemporary multi car systems, as designed by TKE, may be given the name of paternoster as a ‘modern variation’ on an old theme.
