The flora and wildlife of a Peak District garden and its environs — Peter Bull — 19 July 2021

Peter Bull is a retired ENT Surgeon.  He prac­tised in Sheffield but now pur­sues a pas­sion for pho­to­graphy.  He lives on the west­ern edge of Hathersage over­look­ing the Hope Valley, Stanage Edge and Hathersage Moor.

 

Peter has a gift for taking superb pho­to­graphs of wild­life and flora.  His dis­play of over one pho­to­graphs included sub­jects found in his garden and within a mile of his house.

As the title of his talk indic­ates, the pho­to­graphs were all taken whilst we have been in lock­down start­ing in March 2020 and con­tinu­ing up to this month.

Whilst his audi­ence looks in awe at the won­der­ful pho­to­graphs of birds, Peter has included a record­ing of the song of sub­ject to make his talk even more fas­cin­at­ing.  He has two ponds in his garden and he has pho­to­graphed all the ingredi­ents for the witches brew from Macbeth.  He starts with prim­roses, a Black Bird, a Jay, a Dunnock and a Willow Warbler before show­ing superb images of but­ter­flies. He pro­ceeds to show dif­fer­ent images grouped on a monthly basis.  This gves a big range of hab­itat from birds and dragon­flies on the bank of the River Derwent by Leadmill Bridge in summer to stags and white hares in the winter moor­land.

What is so mem­or­able about Peter’s talk is not only the bril­liant pho­to­graphy but the enorm­ous range of anim­als and flora to be found within a mile of his house.

The Sons of George III.  Three Kings, Four Dukes and two early deaths  by Peter Stubbs – 15th March 2021

Peter Stubbs is a retired Sheffield soli­citor with a lifelong interest in his­tory.  His talk takes us back to a very dif­fer­ent time.  Our roy­alty was closely allied to the House of Hanover and the Holy Roman Empire.

George III (born 1738) was King of Great Britain and Ireland from 25 October 1760 until the union of the two king­doms on 1 January 1801, after which he was King of the United Kingdom of Great Britain and Ireland until his death in 1820. He was con­cur­rently Duke and Prince-elector of Brunswick-Lüneburg in the Holy Roman Empire before becom­ing King of Hanover on 12 October 1814. He was a mon­arch of the House of Hanover, but unlike his two pre­de­cessors, he was born in Great Britain, spoke English as his first lan­guage, and never vis­ited Hanover.

In 1761, George mar­ried Charlotte of Mecklenburg-Strelitz and they enjoyed a happy mar­riage, with 15 chil­dren.  After ser­i­ous bouts of ill­ness in 1788 — 1789 and 1801, thought now to be caused by por­phyria, he became per­man­ently deranged in 1810. The Prince of Wales (later George IV) became regent.

George remained ill until his death at Windsor Castle on 29 January 1820.

His first son became George IV of the UK. Born in 1762, he was very accom­plished youth inter­ested in art, music, lit­er­at­ure and archi­tec­ture.  He was con­tinu­ally at logger heads with his father.  At the age of 18 the Prince of Wales was given a sep­ar­ate estab­lish­ment. He threw him­self into a life of dis­sip­a­tion and wild extra­vag­ance.  When 21 he was given an annual income of over £6m plus a grant of £7m in today’s equi­val­ence.  This was totally inad­equate for his life­style.  He was illeg­ally mar­ried to Maria Fitzherbert who he adored and then was forced in 1795 to marry Princess Caroline of Brunswick who he hated. After the birth of their only child Princess Charlotte, they sep­ar­ated and divorced.  His debts in 1795 reached the equi­val­ent of £65m.  His life­style made him very unpop­u­lar with the popu­lace.

In 1763 Frederick (Duke of York) was born, fol­lowed in 1765 by Wilhelm.  Most of George’s sons served in the Army but Wilhelm was regarded as of little import­ance and served as a mid­ship­man in the Navy with no priv­ileges.  He loved the life and became a very com­pet­ent lieu­ten­ant and then a cap­tain of war­ships. In 1791 he began a rela­tion­ship with Mrs Jordan.  She was an act­ress and they were always short of money. In 1818 he mar­ried Princess Adelaide of Saxe-Meiningen.  He rose to become Lord High Admiral.  In 1830 he became King William IV to the great approval of the popu­lace and the Duke of Wellington.  He restored the pop­ular­ity of the Crown.

Space does not permit even a brief resume of the other 12 chil­dren nor the link to Queen Victoria.

A Zoom Magic Show — Richard Reynolds — 21 December 2020

 

Richard Reynolds is usu­ally extremely busy at this time of year with his magic shows but the Coronavirus 19 has meant changes to his modus operandi.  He has devised an obser­va­tion show for audi­ences on Zoom and he kindly squeezed in, at short notice, a present­a­tion for Stumperlowe Probus.

The half hour show starts with a reminder of the Rubik’s Cube.  It was inven­ted by the Hungarian archi­tect Professor Erno Rubick and has been very pop­u­lar from the 1980’s to today.

Various people have achieved incred­ible speeds in solv­ing the game but Richard intro­duces another slant on what to do with the cube and the pat­terns that are cre­ated.  We then move onto gambling card games like “chase the ace”.  Richard con­vinces his audi­ence to never get involved with such as the dealer will through sleight of hand always win.

Lottery cards are his next focus fol­lowed by a ref­er­ence to his interest in psy­cho­logy and people’s sus­cept­ib­il­ity to sug­ges­tion.  He uses play­ing cards and prob­ably sleight of hand to guess the choices that his audi­ence will make.  As a finale he uses the basic sym­bols used by the CIA when research­ing tele­pathy to pre­dict choices that a member of his audi­ence will make.

The half hour “show” flew past with a remote audi­ence very much involved with every second.  It is not easy to fool all of the people all of the time in this situ­ation, but Richard suc­ceeded with dis­tinc­tion.

———————————————————————————-

Then we had a most enjoy­able half hour, as three of our newest mem­bers “took to the floor” to intro­duce them­selves to the rest of the mem­bers. Their life exper­i­ences clearly showed that they will add  greatly to the vast fund of know­ledge within the club. Indeed one has already given us a fas­cin­at­ing talk!

Welcome gen­tle­men!

 

Does wealth lead to health? At home with the de Medici Part 1 by Prof. Tim Stephenson 3rd August 2020

   

The Medici Family Tree

Professor Tim Stevenson has retired as the Clinical Director of Laboratory Medicine at Sheffield Teaching Hospital and is now a member of Stumperlowe Probus Club.  His talk was the first of a two-part exam­in­a­tion of the early Medici family and was given using Zoom.

The story starts with Giovanni di Bicci (1360–1429) who dealt in wool in the Lombardy region of Italy.  He intro­duced and con­trolled a stand­ard system of weights and meas­ures in Italy and cre­ated the Medici Bank.

Giovanni di Bicci (1360–1429)

The weights and meas­ures were used to the Medici advant­age as was the con­trol of units of cur­rency, exchange rates and com­mis­sion rates.  This led to enorm­ous power and wealth.  Greater even than the likes of today’s Amazon, Apple and Facebook com­bined.  The family were great pat­rons of the arts.

The family has two branches headed by Giovanni’s sons Cosimo and Lorenzo di Vecchio.  Cosimo Medici (1389–1464) is asso­ci­ated with Florence and sup­por­ted Brunelleschi and Donatello amongst many artists and archi­tects.

Cosimo Medici (1389–1464)

This branch pro­duced Lorenzo the Magnificent and Pope Leo X (1475–1521) who was patron for Raphael. Plus Pope Clement VII.

Lorenzo di Vecchio Medici

The com­bined houses pro­duced 4 Popes, two Queens of France and sev­eral other kings.  With such power there was much inbreed­ing and ill feel­ing with other power­ful fam­il­ies.  For their phys­ical safety, it was neces­sary to live in for­ti­fied palaces and use tun­nels to travel between build­ings.  Family mem­bers there­fore did not enjoy much direct sun­light and were very prone to debil­it­at­ing dis­eases.

The second part of Tim’s talk is eagerly awaited, where the many dis­ad­vant­ages of such wealth and power will be con­sidered.

Can your arteries tell your age? by Professor Gerald Meininger -24th February 2020

Gerry Meininger is an Emeritus Professor and Investigator at the Dalton Cardiovascular Research Centre at the University of Missouri – Columbia.  He is a very dis­tin­guished speaker who has had a large volume of work pub­lished and has lec­tured all over the world.  Now retired he lives in Sheffield.

The goals of his present­a­tion were to intro­duce his audi­ence to the Cardiovascular System with a little his­tory, a few fun facts and an explan­a­tion of big and little ves­sels.  Next to explain ageing and car­di­ovas­cu­lar change fol­lowed by some of the cur­rent research.  Luckily for the Probus Club, his present­a­tion is clearly struc­tured by many bril­liant PowerPoint slides that illus­trate his entire talk.

The earli­est writ­ings on the cir­cu­lat­ory system were in Egypt in 16th Century B.C. when it was thought that air breathed into the lungs then flows into the arter­ies.  The heart was the seat of emo­tions, wisdom and memory.  William Harvey (1578–1657) declared that the blood cir­cu­lates con­tinu­ously one way around the body.

The aver­age heart is the size of a fist in an adult and it beats 70 to 80 times per minute.  This equates to 115,000 times each day or 2.5 bil­lion times over 75 years.  The heart expels 4 litres per minute and there are only 5 litres of blood in the body.  The cir­cu­lat­ory system in our bodies stretches 66,000 miles.  Capillaries are tiny and are about a tenth the dia­meter of a human hair.

Gerry explained what is meant by large arter­ies are elastic, medium arter­ies are mus­cu­lar and the smal­lest arter­ies are arteri­oles.  He covered the aging effects on elastic arter­ies and on aortic stiff­en­ing and its impact on heart func­tion with enlar­ging the heart.

 

During ageing the large vas­cu­lar ves­sels get stiffer caus­ing hyper­ten­sion and dia­betes.  This effects 1 in 3 people glob­ally.  It also effects the elastic and res­ist­ance of ves­sels.  Aortic stiff­en­ing pre­cedes many med­ical con­di­tions and acts as a pre­dis­pos­ing factor.

Gerry explained the cur­rent hypo­theses about causes of aortic stiff­ness and his recent research into muscle cell ima­ging and topo­logy using atomic force and con­focal micro­scopy.

This was some talk and the Club was very priv­ileged to have enjoyed it.

The secret WW2 listeners of Gilnahirk  16th December 2019 by Professor John Guest

This talk has little to do with John Guest’s back­ground in Biochemistry and much to do with the secret world of Bletchley Park during WW2.  He struc­tured his talk as a jour­ney of dis­cov­ery begin­ning with his later school days in Belfast in 1952 where he was friends with Tony Banham.

Around 1952–53 John was in the RAF Section of his school’s C.C.F. and became involved with glid­ing and he obtained a Gliding Certificate.  He would travel past a suburb of Belfast called Gilnahirk on his way to the Ulster Flying Club at Newtonards by Strangford Lough.  He obtained a schol­ar­ship to read Biochemistry at Leeds University and left Belfast for Yorkshire.

John was intrigued by a book entitled “Gilnahirk’s best kept secret” by Benvista and first pub­lished in 2006.  John had been totally unaware that a radio listen­ing sta­tion had been oper­at­ing in Gilnahirk since the late 1930’s and this was upgraded to a full RSS (Radio Security Service) Station in 1942.  He was even more sur­prised to dis­cover the Officer in charge was Colonel Joe Banham his old school friend’s father.  He set about find­ing his friend who was now Lt. Commander A Banham RN Retired and a photo shows John with Tony together again in 2015.

He dis­covered that Tony’s father had told him very little about his war­time activ­it­ies and his con­nec­tion to Bletchley Park and GCHQ.  John was intrigued and set about trying to find more about this national secret for him­self.

The Wireless Interception Service or “Y” Service were work­ing for four ser­vices: Navy; Army; Air Force and most import­antly Military Intelligence and M18. As the RSS its func­tion was: to inter­cept and record signal traffic; to locate and close down illi­cit wire­less trans­mis­sion; to recruit and manage Voluntary Interceptors and to send signal and data to Bletchley Park.  At the start of the war radio hams all over the coun­try were invited to volun­teer as Interceptors.  Those selec­ted gave at least 2 hours a day listen­ing and log­ging radio sig­nals.  The logged mes­sages were entered onto a stand­ard RSS Log Sheet that was posted to an address in Barnet.  As soon as a Post Office received a letter with this address it was either tele­graphed or sent by des­patch rider to Bletchley Park/GCHQ.  Besides inter­cept­ing for­eign radio sig­nals, local mes­sages were also mon­itored to detect pos­sible spy infilt­ra­tion.  An import­ant part of the activ­it­ies at Gilnahirk was prob­ably to inter­cept radio traffic in the Atlantic and espe­cially sub­mar­ine sig­nals. 

These vol­un­tary Interceptors oper­ated from home, often in roof spaces or garden sheds.  In the early 1940’s there were over a thou­sand listen­ers.

Gilnahirk was involved with intel­li­gence relat­ing to the sink­ing of the Bismark and loc­at­ing the Scharnhorst.

AfterWW2, Gilnahirk con­tin­ued as a wire­less sta­tion through­out the Cold War.  In 1951, it was rebuilt as a brick two storey build­ing that accom­mod­ated hun­dreds of per­son­nel.  In the late 1970’s it was closed down and demol­ished in 2009.  The site has now a block of flats called Gilly Court Manor.

John’s talk is not only fas­cin­at­ing espe­cially to an audi­ence born during the life­time of Gilly wire­less sta­tion but is a reminder of how such things might be recor­ded for the public before memor­ies die out.
