Mr. William F. Friedman, 

310, Second street SE, 

Washington 3 DC. 

Dear· Bill; 

Y~u must have wondered why I havent written long ago. The reasons have 

been maft), above all much to do, many visitors, Bos return from S~uth 

America and subsequent emplaning, with family, for the US, and then 

after all this a rather severe, but not too persevering nervous conditio 

We also had some curious weather lately, with lots of snow, but now it 

seems that spring is on the offensive again. 

First of all I, and with me Annie, want to thank you and Elizabeth so 

very much for all you hospitality, and also for all the interesting 

things you helped me to be able to seal Our stay in the US was a most 

happy and interesting one, and you can take much of the credit for this, - but you will realize that we were rather tired when we came back here. 

Annie went down with flu, and it h~s taken her a long time to recover. 

She is better now, and I trust that she will soon be quite allright aga~ 

Oijr work here is progressing satisfactorily, and we expect to have the 

two first HX-56 ready in a week or so. They are then going to our 

friends in Paris, who will later on show them at some NATO meeting. 

I am satisfied with these prototypes, on the whole. The functions we 

have built 1 nto them are surely what our customers expec't , but there 

will of course be a number of details, which will have to be modified 

so that they will siand up during use. I have especially been critical 

of the construction of the rotors, and while the present rotors will 

probably perform properly in the prototypes, I am going to make some 

interesting /I believe/ changes, which should remove the objections I 

have made against the original construction. 

If you are· at all interested, I will keep you posted on the progress of 

our work. It seems that this year will allow us to progress very aatisfactorlly in several dircictions. 

§ ~ ~ And time flies: We' wont have much more than 6 weeks here in Zug this ~ ::I© .. spring. We will leave for Badenweller in the Black Forest on May 22, 

o ~ ~ return here on June 12, and then go to Sweden a co·Jple of days ill.ater. ~ .c W~ would have liked to be in Sundsvik already on the 10th of June, this ~ ~ <0 being the day our girls and their chl ldren arr1 ve there, but having 

c,> :& ~ -arranged for our 11 cure 11 in Badenweiler already long ago, it was impossib 

ro 0 le to change this. - Q) ..c

Bo sb:uld be in Washington or vicinity one of these days. You will realiz( 

that it is a rather strange feeling, to have him and his family gone. 

But I am sure that he will feel much happier with hls new position, whicl 

will give him a considerable amount of independence. 

I will get Nyberg here in July, 'to fill Bos place, so L shall have a mos: 

competent aide when he comes • 

By the way, our new building will also be ·1ready in July, and then we 

shall be able to do some real manufacturing here.
