Chairman's son appointed Captain of HTP submarine

On 25th June 1955, at a Garden Party at the home of the company's Chairman, Sir Alan Barlow, it was announced that a Barlow son had been appointed Captain of the first experimental HTP submarine, built by Vickers.  I am not sure if it ever went into service - nuclear submarines probably made the HTP method of propulsion (being developed by Germany towards the end of the war) redundant.

Self-Development - e.g. Clear Thinking & Public Speaking

I was attracted by a course on Clear Thinking at the Cambridge Technical College.  The course book was Thinking to Some Purpose by L. Susan Stebbing, who had been Mistress of Girton.  It changed my whole approach to the receipt of information.

After giving one or two talks on behalf of Cambridge Instruments I thought I should improve my presentation skills.  I therefore went with a colleague, John Davis, on a privately provided Public Speaking course.  The culmination of the course was a 10-minute presentation on a topic of my choice.  I chose Aristotle as my subject, probably because I had gleaned from somewhere that he could be regarded as the first scientist.  I greatly enjoyed researching the topic and I got far more of value in later life from the exercise than the development of speaking skills.

It was around this time that I realised I should supplement my lofty "serving humanity" approach by  "serving individual humans".
