The passing of the War Years had taken its toll on Rupert Cropley. His anxiety to safeguard the interests of Grand Lodge during those years, the death on active service of eighteen of his beloved children and the heavy burden imposed by the restoration of the property taxed him to the limit. When the children returned in January 1947, Mr Cropley was a tired man. In June, 1947, the Cropley ‘s   moved from the cottage where they had lived for twenty-five years to new premises at the southern end of the Red Cross Centre, which allowed Mr Turner, the Deputy Superintendent, to live on campus.

Several weeks later, Mr Cropley suffered a heart attack. In spite of warnings by his doctor and his many friends he refused to give up work, as much still remained to be done to restore the school to its former excellence. During his illness he did not miss a meeting of the School Council but from that time Rupert Cropley passed away on September 3rd, 1949 in the Masonic Hospital, Ashfield, aged sixty-eight.

News of his death came as a great shock to students and ex-students of the Masonic School, for as one Old Masonian wrote — 'He was more than the Honorary Superintendent of the School — he was a father to all of us who had lost our fathers.' Mr Cropley had been initiated into freemasonry in Lodge Manorah No. 41 on January 28th, 1909, and to mark the Jubilee Celebrations of Grand Lodge in September 1938, the rank of Past Grand Master was conferred on him.

At the time of his death he was also President of the Masonic School Welfare Fund and Patron of the Old Masonians' Club.  St. Andrews Cathedral, Sydney, was packed to capacity for his funeral service, in which two of his ex-pupils, the Rev. Harold Cterceteko and the Rev. Geoff Fletcher, took part.

In the course of his address R.W. Bro. Archdeacon John Bidwell told the congregation that Rupert Cropley had been the child of a Godly mother who had set him an example and trained him to keep his eyes upon God. In his work amongst the boys and girls he had set them an example as a sincere and noble Christian.

The Grand Master, MW Bro. Frank McDowell, added a further tribute, saying — `Rupert Cropley ’s character was unblemished — one that had the highest possible ideals and traditions. He set before all of us, not only before the children, a standard, which it was very difficult to measure up to. Very few men are given the opportunity to display the talents they possess in the way he has displayed them.' It seemed, however, that as a human being, Rupert Cropley had shortcomings like any other person. Children from 1922 to 1947 who witnessed his assemblies say that he sometimes got carried away when administering the cane. He made favourites among both children and teachers. He was hard on the staff and was often at loggerheads with Miss Runge, the nurse.

At a special meeting of the Old Masonians Club on June 30th, 1950, a subscription fund was opened to install a stained glass window in his memory in the School Assembly Hall. In a few months £700 was raised by voluntary donations and a window depicting Rupert Cropley with two children in Masonic School Uniform was commissioned from artist Bro Radecki. The Grand Master unveiled it 24th, 1951.

Beneath the window appeared the words —

 'I shall pass through this world but once. If, therefore, there be any kindness I can show' or any good thing I can do, let me do it now; let me not defer it or neglect it for I shall not pass this way again.'

The balance from the R. S. Cropley Memorial Fund was spent on a baby grand piano for the Assembly Hall. Mr Cropley ‘s ashes were placed at the foot of the War Memorial and at the request of his wife, the Senior House was renamed 'Cropley House.'

Mrs Beatrice Cropley maintained an active interest in pupils and ex pupils of the Masonic School after her husband's death. She passed away suddenly during a visit to England on August 5th, 1952. Alex Mawhood remembers — 'Mrs Cropley was a gem of a woman. She always had a heart for you and nothing was too much trouble for her'.

The second Superintendent of the School was William Turner, a man of Mr Cropley‘s own choice. From 1950, the four principal officers of the school, William Turner the Superintendent, Stanley McMillan the Deputy Superintendent, Gordon Thompson of the Administration Staff and Frank Waddington the Physical Training Instructor, were all ex-students, raised in Mr Cropley ‘s ways. Gordon Thompson remembers — 'We four had been through the system both as pupils and on the staff and understood the necessity for strict discipline to ensure the place ran to a smooth routine.'

As the task of administering a large childcare program became increasingly complex, Turner was confronted with problems, which never existed in Cropley ‘s day, yet the ratio of staff to children remained the same. The changing economic structure of the post-war community and its accompanying wages explosion caused running costs to escalate. As wages rose and the cost of improved working conditions soared, some awards increased disproportionately causing great discontent among the staff.
