oireachtas

This space was an RDS lecture theater until 1922, so this must be 1922-39. From wikipedia: it was decided to hire the main RDS Lecture Theatre attached to Leinster House for use in December 1922 as a temporary Dáil chamber. The building was bought outright from the RDS in 1924.

The room is octagonal in shape and its original seating capacity was 700. Little alteration was needed to adapt it for parliamentary purposes - the floor was raised and the seating capacity reduced. This photo matches a modern one, so I think it is after the alterations. The DIA says "alts for use as Dail" were from 1925-29, so I think this is earliest 1925.

The RTE stills library has some shots from 1969, no help. The flat wall with the pictures hung on it has been painted white by then, dark in this picture.

I wonder what all the controls on that piece of furniture are for?

McGlade - everything you wanted to know but were afraid to ask and asked about
(Daily Herald - Thursday 02 January 1913)

Bernard McGlade. Leicester Chronicle - Saturday 05 November 1898:

At Dublin on Saturday Mr John Doyle, confectioner, recovered 20 guineas damages from Bernard McGlade, billposter, for libel and conspiracy to slander. Mr Doyle had ceased to employ a trade unionist, and as a consequence of this action the trade union employed Mr McGlade to distribute circulars through the streets exhorting the public to have nothing to do with Doyle's confectionery.

More detail in Cotton Factory Times - Friday 04 November 1898:

The plaintiff's case was that a trade union official Game to him and told him thnt as he had ceased to employ a man who refused to work unless employed by the week, and had taken on another man by the day, he must "beware of himself." The next day and on some following days a man dressed as a clown, who was in the defendant's employ, stood Opposite the plaintiff's house and handed to the people who passed a handbill with the following offensive contents : " Rats I Rats! Rats! at J. G. Doyle's, Capel-street. Scab labour at J. G. Doyle's. Outcasts of Confectioners' Trade Union at J. G. Doyle's. Down with scab labour. Exterminate the Rats ! Rats! Rats!"— The plaintiff gave the man into custody, but the magistrate said he would not punish him, as the real criminal was McGlade.

and

In the meantime though McGlade ceased to send out bills the prosecution of the plaintiff did not cease, boys being sent to the shop who shouted out to customers " Don't go in and take scab cakes and sweets,t;" and to plaintiff's girls when they went out, "rats."

1901 census Bernard McGlade of Middle Abbey Street, 44, profession mistranscribed as 'pill porter', married with 4 children, one of whom is also a 'bill porter' (although either his wife Fanny's age is wrong or they were from a previous marriage). In the 1911 census the children have flown the nest, his wife (now Margaret) is the regulation 10 years older but Bernard is only one year older.

John Spooner Thank you, John. We asked if we could find out anything about Mr McGlade, but never dreamed of a story involving a henchman "... dressed as a clown"!

Dublin Evening Telegraph - Monday 1 August 1904: "The Oireachtas, the annual festival of the Gaelic League, was opened today at the Rotunda, and will continue each day during the week." Or possibly 1910, when it opened on Monday 1st August. (Evening Irish Times - Tuesday 2 August 1910)
