"At that time she connected with Brian Haselgrove when they both joined a music group, which listened to 'long playing records', a recording and playback technology that intrigued them both."

Married Brian Haselgrove at St Luke's Church, Goostrey and afterwards at Jodrell Hall (Terra Nova School).

Some wedding photos taken by her aunt Dorothy.

Son, Richard D Haselgrove, born.

The Radio Science Bulletin June 2008 published honouring the contribution Jena made to the radio science world with her research papers published in the 1950/60s. She used the first UK general purpose stored-program computer EDSAC commissioned at Cambridge in 1949.

Jena developed the 'Haselgrove Equations' which were applied to radio propagation in the ionosphere.

References to the papers she produced whilst a research student at Cambridge:

The tribute was continued in the December edition of the Radio Science Bulletin.
